One - unum

I used online english-latin dictionaries to find these but since I don't speak latin, I can't vouch for their accuracy.

I'll vouch for them

If you had to find "one" in a dictionary, it would most likely be "unus", though, as that's the masculine form. -And if you mention "tria", you'd probably mention the feminine version of every numeral, which isn't really necessary.

A transcribed version of the ancient Greek goes something like this:
heis
duo
treis
tettares
pente
hex
hepta
okto
ennea
deka

(not sure if I got the transcription right, some of the sounds (viz. "u" in duo and the last "o" in okto) are a bit difficult to describe with latin letters)

And the Danish (much easier):
én
to
tre
fire
fem
seks
syv
otte
ni
ti

Oh, and the French, as far as I recall:

un
deux
trois
quatre
cinq
six
sept
huit
neuf
dix

-or something along those lines

Dutch:

een
twee
drie
vier
vijf
zes
zeven
acht
negen
tien

Hmmm... yes, it's normal to write "én" or even "een" for 1 in Danish, but I'm quite sure the official spelling is just "en" and "et".

Yes, you're right (of course) about the official spelling, but when you use the numerals for counting, it's pronounced and (I believe) more often than not spelled with an accent, én.
