The English number nineteen is translated into French as dix-neuf.

Meaning: cardinal number (num)

What does it mean word for word?

The word is a compound of dix (ten) and neuf (nine).

dix-neuf is a masculine number.

/diz.nœf/

The word neuf in dix-neuf shares its spelling with the French word for 'new'.
The French word dix is a distant relative of the English word 'ten' through their shared ancestor in Proto-Indo-European. They both evolved from a root meaning 'ten', though the sounds diverged over millennia.
The pronunciation of dix-neuf features a 'z' sound (liaison) between the two words, which is a phonetic requirement that doesn't exist when saying dix on its own.
