There are two meanings, though only one appears in everyday conversation. In classical music, forte means “Play This Loudly!”. It’s said FOUR-tay since the word is of Italian origin. However, the common meaning of forte is “strong point” as in, “Cooking classic French cuisine is my forte”, or “Getting into bad relationships is his forte.”
If you want to sound smart, make sure you are saying the word correctly. It is pronounced ‘fort’ with no vowel sound on the end.
