I checked with google translate and it told me that anchovy, singular, is acciuga, and anchovies is acciughe.
How do you remember that e in Italian is feminine, whilst O is masculine singular, and i is masculaine plural?
Spaghetti is maculine plural. E is feminine, like the e in she. Like the French ette, elle as in belle, onde, add e for the feminine, as in French blond is a male with yellow or light hair, whilst blonde ending with e is a woman.
