Read the whole thing:

In Japanese cuisine, sushi (寿司, 鮨, 鮓, sushi?) is a food made of vinegared rice combined with fish (uncooked and in some cases cooked).

Sushi is an English word that has come to refer to a complete dish with rice and toppings; this is the sense used in this article. The original term Japanese: 寿司 sushi (-zushi in some compounds such as makizushi), written in kanji, means snack and refers to the rice, but not fish or other toppings.
There are various types of sushi: sushi served rolled inside nori (dried and pressed layer sheets of seaweed or alga) called makizushi (巻き) or rolls; sushi made with toppings laid with hand-formed clumps of rice called nigirizushi (にぎり); toppings stuffed into a small pouch of fried tofu called inarizushi; and toppings served scattered over a bowl of sushi rice called chirashi-zushi (ちらし).

cold boiled rice moistened with rice vinegar, usually shaped into bite-size pieces and topped with raw seafood (nigiri-zushi) or formed into a long seaweed-wrapped roll, often around strips of vegetable or raw fish, and sliced into bite-size pieces (maki-zushi).
