I just wanted to 'thumbs up' the Michel Thomas reference.  For English speakers wanting to study major European languages, it is a great place to begin.

Here is a BBC program about Michel Thomas, in three parts:

Thanks Jane, Michel Thomas says on his French CD that 60% of the English language are French words. In fact all English words ending in; ible, able, ent, ant, ical, ance, ence, ary... are from French, and the list continues.

You are right, I should have included 'Aperitif', we use that in restaurants all the time.

Thanks Norman Invasion.

I just thought of something, most of the French words above are actually the English word. There is no other English word for cuisine or souvenir, we use the French word.

There is also the word Affaire

Like in " love affair "

And many words related to dating and gallatery
