Linguine (also spelled linguini, which is an anglicisation) are a form of pasta — flat like fettuccine and trenette, but narrow like spaghetti. The name means "little tongues" in Italian. Linguine originates from the Campania region of Italy. Linguine alle vongole (with clams) is a popular use of this sort of pasta.
Whilst spaghetti traditionally accompanies meat and tomato dishes, Linguine is often served with seafood but also pesto. Linguine is also slightly wider than spaghetti.It is also used in the place of spaghetti.
