I was going to do this one a while
ago but never got around to it. But now I am! More numbers! Let’s see where the
names come from.
Ten
Ten
comes from the
Old English ten,
so we’re not looking at any major changes. It’s from the
Proto
Germanic tehun, from the
Proto Indo European dekm-, which meant
ten. Of course that’s a part of a lot of other numbers, some of which make sense,
like
deca-,
deci-, and
-teen, but there are also a weird
number of other words that you wouldn’t think it would be related to, like
dean. Seriously, dean, as in the dean of a college.
Why? Because it once meant the head of a group of ten. And dekm- is also the
source for most of the other numbers we’re looking at today.
Hundred
Hundred
comes from the Old English
hundred, so once again we’re not looking at anything crazy here. It’s from the Proto
Germanic
hunda-ratha, and the ratha-
means reckoning or number, while the hunda- part is actually from
hundam, which also meant
hundred—hunda-ratha meant hundred number. It’s from the Proto Indo European
km-tom, no I don’t know how to pronounce
that even though I badly want to, and that word is from another,
dkm-tom-. And that dkm- is from dekm-.
We just kept dropping letters there. Seriously, first the E, which is a vowel,
so you can still figure the word out, but then the D, and then between the PIE
and Proto German the K became an H. What were they thinking?
Thousand
Thousand
comes from the Old English
þusend,
which is just
thousand with a thorn
in place of a th. It’s from the Proto Germanic
thusundi, and beyond that, things get a little murky. It’s thought
to be a mix of Proto Indo European roots,
teue-,
to swell, and our old friend dekm-,
making the word something like “swollen-hundred”, I’m not kidding, that’s what
the etymology dictionary translates it as. Basically, a swollen-hundred was a
great multitude, in the same way we might hyperbolically say there are thousands
of something to express that there’s uncountably a lot.
Million
And now for a word that actually
isn’t related to all of these. Well, kind of. Million has an actual time frame
for its arrival, having shown up in the
late fourteenth century as
milioun. It’s from the
Old French
million, which is from the Italian
millione, which figuratively meant a
“great thousand”. See, in Italian,
mille
means a
thousand,
as it does in
classical Latin.
Because the Italians called a million a great thousand, we have million in English—as
well as
billion,
trillion,
and anything else we want to stick in front of -illion.
