Why are the Russian(Slavic) numbers 9 and 10 so similar?

9: nine(English)-neuf(French)-devyat(Russian)-devet(Bulgarian)
10: ten(English)-dix(French)-desyat(Russian)-deset(Bulgarian)

Compared to English or French, the Slavic numbers 9 and 10 look so similar!
Why are the Russian numbers 9 and 10 so simiar to each other?
"devyat(9) and desyat(10)"

Do the numbers have the same etymology or origins?

Haven't you also noticed how English number 'six' and English word 'sex' are similar? Interesting, no?
Btw, I've always wondered why are the Japanese numbers 9 and 10 or 'ku' and 'ju' so similar.

The English example you gave above is purely coincidental. "Six" comes from Anglo-Saxon from Proto-Germanic from Proto-Indo-European. The other word that you mentioned I believe comes from Latin.

It does appear that the Slavic word for 'nine' breaks from the Indo-European pack in that it does not have the initial n- or en- sound.

I wonder if Old Church Slavonic 'deveti' was originally linked to the word for "ten", 'deseti', i.e. "ten [minus one]"

Does anyone know?

first of all, English and French do not belong to the same linguistic group (one is Germanic language, the other one is Romance)

second: it's not deveti or deseti because those numbers you wrote are cardinal

Does that really change the substance of what's being asked?

Does somebody need a hug today? >: )
