And - Etc...
You already know the Latin word for "and". It's the et in etc. (et cetera - and other things) and et al. (et alia - and other people). Here's what the Romance languages did to it:
French for "and" is et, pronounced "ay" (never, ever "ette").
The Italians followed one step further and got rid of the "t" altogether:
Italian for "and" is e, pronounced "ay".
Spanish for "and" is y, pronounced "ee" - still a single vowel sound, but a different one, so it's not the French wrecking the pattern for once.
