Back to "forte" for a minute. I've never heard it pronounced "fort", ever. In French the feminine forte, meaning "strong", it would be pronounced "fort" LOL. There is no accent on the "e". (The masculine "fort" is pronounced "for".)[
The Italian "forte" means "loud" and is frequently used in musical notation. It's always prounouned "fortay". In fact the well-known keyboard was originally called a "pianoforte", or "soft-loud". There is also "fortissimo", or, very loud!
I've always thought that even though most people say "for-TAY" it was actually supposed to be pronounced "fort." No accent aigu on the E, and not a silent T like "for," but acknowledging that in French a final unaccented E is a signal to pronounce the last consonant (as in "monde"), so "fort." (Which then always seemed to me to require a French R, a semi-rolling back-of-throat sound, but that was probably just me.)
Thanks to several years of piano lessons in elementary school, I was also familiar with the Italian forte. But I always thought the word we use to mean "strength" (which the Italian one kind of means, too) was the French.
Now, though, several full minutes of googling yesterday led me to believe you can pronounce it however the hell you want. Since I usually use it to mean "area of expertise or skill" -- which isn't even exactly what it means in French -- I'll probably stick with my current habit, which is usually to deflect to "strength" or "strong suit."
