Hi, I'm Stephen Turton, and this is Etymology Support.
[upbeat music]
First question.
SamuelM80056720 asks,
I have a semi-serious question for etymologists.
If feet is the plural for foot,
why is beet not the plural of boot?
Is it because of the vegetable?
Foot belongs to a category of words
that derive from Old English in which to make the plural,
you change the vowel in the word.
So other words in this category
are tooth-teeth, and goose-geese, mouse-mice.
Book also used to be in this category in Old English,
but later on we regularized the spelling,
so it's book-books.
If we'd kept the Old English pattern,
it would now be one book, two beech.
The word boot, on the other hand, is not from Old English.
It was borrowed from French into Middle English,
which is why it just gets the default plural -s.
There are lots of different ways of pluralizing nouns
in Old English.
So you might form the plural
by changing the vowel in the base word,
or you might form the plural by adding a suffix,
which could be, -as, -a, -an, -u, -ru.
In the Middle English period most of these ways
of forming the plural fell out of use
and the -s plural came to predominate.
So it basically replaced the old plurals
for a lot of English words just because it was easier.
SharPhoe asks, Weird etymology question.
When and why did whoops/oops
become the default sound made when making a mistake?
So, whoops is actually more recent than you might think.
The earliest evidence we have of whoops being used
in writing dates to the 19th century.
It actually seems to have been derived from oops-a-daisy,
which we have slightly earlier evidence for.
Oops-a-daisy might have been
a kind of whimsical alteration of lackadaisy,
which is in turn a whimsical alteration of alack-a-day,
which is in turn a whimsical alteration of alack,
which is a very old way of saying, oh no.
This is from the FindingFennsGold subreddit.
Origin of the word clue.
Clue originally meant a ball of thread.
Then, during Middle English it came to be associated
with the Greek myth of Theseus
who used a ball of thread to find his way in and out
of the Minotaur's Labyrinth by unspooling it on the way in
and then following it back out.
From this, a clue came to mean
something that helped lead you to a solution to a problem.
And that is now the only meaning
which is common in English today.
RonilBBK asks, Silent letters in words
don't make any sense.
How about you just don't add the letter in the word?
So there are a couple of reasons
that silent letters exist in English.
One is that the pronunciation of the language has changed
and the spelling system just hasn't kept up with it.
For example, the G-H in words
like through and thought and night.
The G-H exists there
because that sound used to be pronounced.
In Old English and Middle English,
that was the velar fricative [vocalizes].
Eventually, because that's quite a difficult sound
to pronounce, it dropped out of the language,
but we continue to spell words with that G-H
through a process of sheer inertia.
There have been calls for spelling reform in English
for literally centuries.
In the 19th century, one author complained
that the word fish might as well be spelled G-H-O-T-I.
G-H, as in the f at the end of rough,
O as in the i in women,
and T-I as in the sh in mention.
Now, in reality no would actually spell fish this way
because we know that there are implicit rules
to where letter combinations can go in words.
So we know that G-H can stand for the sound f,
but only at the end of a word, as in rough, enough, tough.
There was also a moment in time where a word like mention
would've been pronounced ment-i-on or something like that.
But the T-I-O-N in English,
if you say it enough times over and over,
tion, ti-an, ti-an, chi-an, chi-an, chin, shin,
it just becomes a lot easier to say shin.
So T-I I becomes sh.
Ease of articulation is a common trigger
for sound change in English and other languages.
Crowzur asks, Why do question words,
why, who, where, when, et cetera, all start with WW-H?
So this goes all the way back to Proto-Indo-European,
which is the earliest ancestor of the English language
and many other European and Asian languages
that etymologists have been able to reconstruct.
Proto-Indo-European had an interrogative stem,
an element of a word that would go into building other words
that looked something like qui.
And this and its variants were used to coin question words,
And this qui survives into many modern languages.
So for example, in French and Spanish as Q-U
as in qui, que, quando, quel.
It also survives in English as W-H.
And the resemblance is easy to see
once you know that the original spelling
and pronunciation in English was H-W, hua.
Nobody ever actually said wa-ha.
If you listen to older speakers today
who still pronounce the H in these question words,
you will hear that they put the H before the W.
So it's what, why, when.
At jpk_murphy asks,
Wonder where the word salary originated.
So the word salary comes from Latin salarium,
which ultimately comes from sal meaning salt.
In ancient Rome, a salarium was a wage paid to somebody
so that they could buy salt and other household goods.
The word salad ultimately derives from the same root, sal,
because a salad was a cold dish that was seasoned with salt.
This comes from the etymology subreddit.
What's going on with the word child?
Why does it pluralize into children rather than childs?
Child goes all the way back to Old English,
which had multiple methods of forming a plural.
One of the plurals for the word child in Old English
was childru.
During Middle English, this became childre.
However, at a later moment in time for some reason
people decided that this didn't look enough like a plural,
so they added a second plural ending N,
as in ox-oxen, to create the word children.
So it actually has two plural endings
stacked on top of each other.
It's equivalent to saying childses.
Delarosajl24 asks, Why do we call it deadline
for when something is due?
What does death have to do with finishing projects on time?
So this is a bit of a grizzly story.
During the American Civil War,
a deadline was a literal boundary around a prison
that prisoners were not allowed to cross
without being in danger of being shot.
From that, a deadline came to be used metaphorically
to mean a point of no return.
And that's why we get the sense of a date
on which something is due.
Jbud3570 asks,
Why are there multiple words that mean the same thing?
There are actually very few true synonyms
in English or in other languages.
You know words that have exactly the same meaning
in all contexts.
Even if two words appear to have exactly the same meaning,
they will tend to be used in somewhat different contexts.
For example, big and large,
you could say that you have big ideas,
you're a big spender, but then you end up in big trouble.
However, no one would say that they have large ideas,
they're a large spender, or they end up in large trouble.
And that's because we're very comfortable using the word big
in literal and figurative contexts,
but we prefer to use the word large
only with its literal meaning.
Sometimes multiple synonyms exist
because of language borrowing.
For example, in English we have the words
kingly, royal, and regal.
They all mean the same thing,
but kingly comes from English king,
royal comes from French roi, meaning king,
and regal comes from Latin rex, also meaning king.
Dworkphone asks, Is there any reason
for the alphabet being in the order it's in?
The clue is in the name.
The word alphabet comes from alpha beta,
which are the first two letters of the Greek alphabet,
and they correspond to Latin A and B.
Exactly how the letters ended up in this order,
A, B, C, or alpha, beta, gamma,
or ah, ba, ca, or ah, ba, ga is not known.
It might have been random to an extent,
but it's also worth noting that a lot of these sounds
are the first sounds that human babies make
when they first start babbling,
a, a, ba, ba, ga, ga, ca, ca, da, da.
The Latin alphabet ultimately derives
from the Greek alphabet,
which in turn ultimately derives
from the Phoenician alphabet.
And in all of these alphabets,
the letter orders starts out in the same way,
although the sounds attached to those letters
aren't exactly the same.
When the Latin alphabet spread to other languages
in Europe and beyond,
they tended to keep the same order of letters.
This is a question from Quora.
Why do some languages have formal
and informal versions of you, but English does not?
There's a bit of backstory to this question.
Initially, English had two second-person plural pronouns,
thou and you,
Thou was for addressing a singular person,
you was for addressing more than one person.
However, over time, because of the influence
of French in which the plural pronoun vu
can also be used as a polite pronoun,
you became a respectful way
of addressing a single person as well.
And at that point, thou started to fall out of use.
Because if you was the respectful way
of addressing one person, then if you called someone thou,
it implied that you disrespected them.
So after that happened,
thou eventually fell out of the language.
So English was left with you
as its only second-person plural.
Obviously, the problem with this
is you can no longer easily distinguish
between singular and plural.
What some people have since done
is they have coined new second-person plural pronouns
like y'all and yinz in Pittsburgh,
and yous which is used in Scotland
and Ireland and some other places.
Ganson asks, Why do we say it's raining cats and dogs,
but not any other animals?
There are a couple of theories about
where this expression came from.
Some people say that it's because medieval people
used to keep their livestock and pets on the roof
and during heavy rain they would fall through the thatch.
Seems unlikely.
Other people say it's because during heavy rains
dead animals in the gutters of London
would float down the streets.
But it's worth noting that there is an earlier idiom,
which is they agree like cats and dogs,
which means two people don't agree at all,
they're constantly fighting.
So it's possible that that meaning
then informed the expression it's raining cats and dogs,
as in it's raining so hard,
it's like the weather is fighting outside.
Yokernat asks, Does the language you speak
make you feel and think differently?
And if, how so?
So, linguistic determinism is the technical term
for the belief that the language we speak
fundamentally controls and limits the way we can think.
In the strong form, this obviously isn't true.
If it were true,
we would never be able to learn a new concept
unless we already knew the word for them,
and we also wouldn't be able to learn a second language
unless it's vocabulary mapped
exactly onto our first language.
But there is a weaker version of this hypothesis
called linguistic relativity,
which is just the suggestion that yeah,
maybe language does affect the way we think to an extent.
And there is some evidence for this.
For example, some linguists did a study
where they showed native speakers of German and Spanish
a series of pictures of objects.
And it just so happened that those objects
had names in Spanish and German
that had different grammatical genders in the two languages.
And what they found was when they asked speakers
of those languages to describe the objects they saw,
the speakers would tend to use adjectives
that reflected certain cultural gender stereotypes.
So for example, they showed them a picture of a bridge.
In Spanish a bridge is puente, which is masculine,
and Spanish speakers tended to describe the picture they saw
as big and strong.
But when they showed the same picture to German speakers
for whom bridge is brucke, which is feminine,
those speakers tended to say
that the bridge was beautiful or elegant.
So clearly there is some bias
that goes into how we think about language,
but that doesn't mean that a speaker of German
would be incapable of imagining a bridge as masculine.
Sometimes you see posts on social media of people saying,
Here's this word in my language
that is untranslatable into other languages.
Welsh word hiraeth, which means a sense of longing
for something, possibly home, possibly something else.
But the thing is you can actually translate
these words into other languages.
I just translated hiraeth into English,
I just have to use a sentence
rather than an individual word.
But clearly we can translate concepts
from one language into another.
Just because we don't have a direct single word for it
doesn't mean that we can't fully grasp what it means
in another language.
And if we really want to,
we can always just borrow that word
from another language into our own.
AXDAJQ asks, Why do we say break a leg
to wish someone good luck?
Wouldn't breaking a leg be the opposite of good luck?
The expression break a leg originates in the theater
where superstitious actors thought it was bad luck
to wish someone good luck
and good luck to wish someone bad luck.
DerekAtTheChase asks, I am curious.
How do etymologists/wordsmiths
determine the pronunciation of Old English words?
Thinking emoji.
So there are a number of ways etymologists do this.
One thing is that luckily Old English
was a lot more phonetic in its writing system
than modern English is.
There was much closer match between how words were spelled
and how they were pronounced.
Old English also borrowed its alphabet from Latin,
and it happens that a lot of the sounds those letters had
in Latin are the same sounds they then had in Old English,
which makes it a lot easier.
We know what modern German and Dutch sound like.
We know what modern English sounds like.
So from that we can reconstruct what earlier forms of words
in those languages might have sounded like
and how they might have diverged
based on regular processes of sound change.
For example, we have the word night in modern English.
It's spelled N-I-G-H-T.
In Old English, it was typically spelled N-I-H-T.
We know that the German word for night is nacht,
which has this velar fricative sound at the end [vocalizes].
And so based on the spelling in Old English
and the fact that this velar fricative sound
has survived in other Germanic languages,
we can conclude that in Old English
night was pronounced nicht.
JakeUnusual asks, How do new words form,
get approved, and get added in the dictionary?
Okay.
[book slams]
This is volume one of The OED.
It goes from A to bouzouki.
I couldn't bring the whole thing with me
because it is 20 volumes long.
The Oxford English Dictionary is an attempt
to document every word pretty much
used in the English language
from the year 1150 to the present day,
which is why it keeps getting longer and longer.
So in theory, words should never be taken out
of The Oxford English dictionary,
although in practice sometimes they are.
So this is basically the mother of all dictionaries
in English.
Any word that enters the language
and gets used by enough people
and stays in the language for long enough
will be added to the OED eventually.
Quo210 asks, Why do Americans say the bee's knees
to refer to something amazing?
The bee's knees originated in the 1920s
in the flapper culture.
That's when a woman wore long necklaces and short dresses.
Bee's knees was one of a number of phrases that people used
to suggest that something was beyond compare.
Another one is cat's pajamas, which still survives,
but there are also a host of others that we no longer use
like the eel's ankle, the sardine's whiskers,
and the elephants in step,
which I think we should bring back.
This question comes from the NoStupidQuestions subreddit.
Why the [beep] are pineapples called pineapples
when they ain't got [beep] to do with pine or apples?
So, pineapple originally meant a pine cone,
and when Europeans first encountered pineapples,
they thought they resembled pine cones.
That's where the word comes from.
But the apple is basically the default fruit
that Europeans use for talking about
new fruit they've encountered in other parts of the world.
So a potato used to be known as an earth apple,
which is modeled after French pomme de terre.
A tomato used to be called a love apple, no idea why.
Dunno what it has to do with love.
This is from the AskSocialScience subreddit.
Why did we stop using words like thou and hath
and words with -eth on the end?
So words like hath, doth, goeth, words that end with T-H,
reflect the original way of marking a verb
to show that it had a third-person singular subject
in English, so he goeth, she hath, it doth.
Roundabout the Middle English period,
this -eth started to fall out of use
and it was replaced by -S, so she has, he has, it does,
which is still the form we use today.
Today, we most associate words like hath
with the works of William Shakespeare
or the King James Bible.
But interestingly, even though the word hath
was commonly spelled around this time in the early 1600s,
it had already fallen out of use in the spoken language.
So we actually have a spelling book from this time
that tells young students
that although we write the word hath and doth,
we pronounce them as if they were written with an -s,
has and does.
So this is an instance where writing
has taken longer to catch up with the spoken language.
Busy-Consequence-697 asks,
Do people really use those funny collective nouns,
murder of crows, et cetera?
I mean, I guess people can use these words
if they're feeling whimsical enough.
So these collective nouns started out life
in the Middle Ages as hunting terms.
That's where we get phrases like a gaggle of geese,
a herd of deer, and a siege of herons.
They quickly spread to other domains of use,
often with humorous intentions.
So the 15th century Book of Saint Albans, for example,
gives us a long list of collective nouns,
including a drunkenship of cobblers,
an eloquence of lawyers, and a superfluity of nuns.
Neurotic-parents asks, How did the word okay
come to be used in so many languages
with practically the same meaning and pronunciation?
Okay originated as an abbreviation of all correct
in the US in the 19th century.
There is a theory that originated in the army
where a particular general used to sign off documents
as okay because he didn't know how to spell
all correct properly.
We don't have any evidence of that
and it seems more likely
that it was a deliberate joking misspelling of the words
to indicate that actually things were just adequate
rather than entirely satisfactory.
The first evidence we have for it comes from newspapers.
This is from the AskHistorians subreddit.
Did people actually talk how Shakespeare wrote?
Yes and no.
Putting aside the fact that Shakespeare wrote in rhyme
and iambic pentameter a lot of the time,
he also lived at a time of intense linguistic creativity.
So, writers of all kinds were eager to coin new words
or use old words in new ways.
So much so that some people actually complained about this
and objected to the rise of what they called inkhorn terms.
An inkhorn is a vessel
in which you would keep your ink for writing.
So an inkhorn term is a word that never had any real life
in the language.
It's almost as if you've just plucked it
straight from your inkwell on the end of your quill.
In everyday language,
most speakers would not have had such a vast vocabulary
or contorted grammar in such unusual ways.
@jesse_cassino asks,
Alexa, what's the origin of the word quarantine?
Quarantine comes from the French quarante, meaning 40,
which ultimately comes from a Latin word
meaning the same thing.
Originally, a quarantine was a period of 40 days
set aside for a special purpose, like fasting.
It then changed to mean a period
during which somebody was isolated from a community
to prevent the spread of disease.
A Quora user asks, How do words change meaning over time?
Semantic change is a regular feature
of all living languages.
There are a number of common processes
through which words change their meaning.
One process is narrowing,
which is when a word's meaning becomes more specific.
So for example, the word girl in Old English
meant a child of any gender,
but then it's meaning narrowed to mean only a female child.
The opposite process is broadening,
which is when a word's meaning becomes more general.
For instance, the word bird used to mean a little chick,
a nestling, a fledgling,
and it was only later that it came to mean
a fowl of any age.
And at that point it started to replace the word fowl
in the rest of the English language.
Another process is amelioration,
which is when a word's meaning
becomes more positive over time.
The word nice originally meant foolish.
It then came to mean fussy,
then it came to mean meticulous,
then it came to mean delicate,
then it came to mean attractive.
The opposite process to amelioration is pejoration,
which is when a word gains a more negative meaning.
So kind of in the opposite process to the word nice,
the word silly used to mean holy or blessed.
It then came to mean innocent or harmless,
then it came to mean helpless,
and then it came to mean foolish.
This is from the etymology subreddit.
Why does cow, pig, sheep, all have different names
when referring to them as food, beef, pork, lamb,
but chicken, fish, or rabbit stay the same?
The words beef, pork, and mutton
were borrowed into English from French
after the Normans invaded England.
At that point in time,
French became the language spoken by the nobility.
The author Walter Scott suggested that the reason
we had these pairs of native English words
like cow, sheep, and pig versus French words for the meat,
so beef, pork, and mutton,
had to do with the fact that English-speaking peasants
would raise these livestock and then they would be eaten
by the French-speaking nobility.
The reason that rabbit doesn't have a separate word
is that there was no native English word for rabbit
because they didn't exist in England
until the Normans brought them over.
Tiny-Werewolf-4650 asks,
Why aren't English words pronounced
as the way they are written?
There are a couple of reasons that English pronunciation
divots from English spelling.
One is sound change.
Words have changed the pronunciation over time,
but we haven't updated the spelling to match.
Another reason is language borrowing.
So English has borrowed a lot of words from other languages
that have their own different spelling systems,
and sometimes these spelling systems
have been partly imported into English.
For example, in English words that have P-H pronounced f,
like physics or phlegm,
are all borrowed from Greek where there is no letter F.
Another reason is folk etymology,
which is when people change the spelling
or pronunciation of a word due to an erroneous belief
that it's related to another word.
So a good example of this is the word island.
Island comes from Old English iegland.
It did not have an S in Old English.
But during the Middle English period,
English borrowed another word meaning the same thing
from French, isle, which English now pronounces isle.
The reason that isle or isle has an S in it
is that the French word
ultimately derives from the Latin word insular.
So people thought, well, there's an S in insular,
therefore we should put an S in isle,
even though the S was always silent
in English and in French.
And once this had taken place, people thought,
Wait a minute, we have these two words, isle and island.
They must be related.
And so they inserted a silent S
into the word island as well,
even though historically
there is no reason for it to be there.
MecHR asks, Why is it that some sayings
between certain languages are the same?
There could be two reasons why two languages
have very similar idioms.
One could be because there are some basic metaphors
that many languages share.
For example, the Spanish idiom [speaking Spanish]
means literally to throw wood on the fire.
In English we would say to add fuel to the flames.
But they both mean the same basic thing,
which is to make a bad situation worse.
The reason they could be so similar
is just that the idea that conflict or danger equals fire
is one that is found as a basic metaphor in many languages.
Another reason that languages could have similar idioms
is because one language has just literally translated
an idiom from another language.
A Quora user asks, Why is the word muscle
pronounced mussel?
So muscle is one of a group of words in English
where there's a silent letter in the base word,
but then that letter gets pronounced in an adjective form.
Other words in this category include condemn
to condemnation and phlegm to phlegmatic.
The reason for this has to do with rules
around syllables structures in English.
There are certain combinations of consonants
that are not allowed to occur together
at the beginning or an end of an English syllable.
So for instance, the sound sequence muscle, S-C-L,
is not really permitted in English syllable structures,
so instead we drop the C.
However, in the word muscular,
a U is added to the middle of the word
and that breaks up the syllable boundaries
so that now we have mus-cu-lar.
That consonant cluster no longer exists.
The word muscle comes from Latin musculus,
which literally translates as little mouse.
Apparently the Romans thought
that muscles look like small critters
running up and down your skin.
EdLincoln6 says,
Words with the same spelling and pronunciation,
but different etymologies.
So these would be known as homonyms,
for instance bat as in the winged creature
and bat as in the stick of word.
Some of these are true homonyms,
as in they come from separate roots,
but actually a lot of words that look like homonyms
do share a root.
For example, bank as in a riverside
and bank the place where you keep your money,
these actually derived from the same Germanic root,
which originally meant a slope.
From there, it came to mean a shoreline,
the land sloping down to a river,
and also a counter on which you would exchange money.
ColomboSabani asks,
How do etymologists even find out the meaning of the words?
How do they know where to look back to?
So, it is rare for words to appear out of nowhere.
A new word is often a blend
or a compound of two existing words,
or it's an existing word that's changed,
a noun has become a verb or an adjective has become a noun.
If none of those cases apply,
then an entomologist will look at other languages
that the word might have been borrowed from,
and they'll try to trace back
the earliest known use of that particular word.
What an entomologist will have to do
is to compare the word they're looking at
to other words in languages they know to be related,
and then reconstruct from the evidence
what an earlier form of that word might have been.
For example, an entomologist would work out
that the word disaster in English
comes from Italian disastro.
From there, they would work out that dis-
is a negative prefix, astro means star,
so disaster or disastro literally means an event
that happens under a bad star.
Chatongie asks, What is that R like sound I hear
between vowels when you say something like,
'Did you eat?' but sounds like, 'Did youreet?'
Or, 'The idearof blah blah,' when meaning the idea of?
So this is known as intrusive R
and it's a way of resolving vowel hiatus.
So vowel hiatus is when two vowels in separate syllables
come together without a consonant separating them.
English speakers are very uncomfortable about this,
and so when it happens we'll often insert an R
to break up the hiatus.
So for example, this ice cream tastes bananary.
So people will insert an R as a way
of avoiding the vowels being together,
for instance in an expression like Africa and Asia.
Rdfporcazzo asks, Why is the letter R
pronounced so differently in each language?
So the letter R can be pronounced as an approximate er,
as an alveolar trill [trills], as a uvular trill [trills],
or as a tap [vocalizes],
and that's just in languages in Western Europe.
It's thought that in the Middle Ages
most Western European languages
used an alveolar trill [trills].
However, in the early modern period
the uvular trill [trills]
started to become fashionable in France
and then later in Germany.
And in English around the same time,
the trill [trills] was replaced with the approximate er,
which is easier to say,
although it doesn't sound as good.
One of the major reasons for sound change
is ease of articulation,
that and changing fashions.
There's often no more logic to it than that.
I hope you learned something today.
Thanks for listening.
See you next time.
