It’s a common misconception that sushi literally means “raw fish”. However the word actually refers to the vinegared rice used in the popular Japanese dish.
Sumeshi (sushi rice) is prepared with gently folded rice and a rice vinegar, salt, and sugar mixture. Traditionally, sushi is topped by raw fish, cooked seafood, fish roe, egg, and/or vegetables such as cucumber, daikon radish, and avocado.
Popular types of sushi include nigrizushi (hand formed sushi), makizushi (rolled sushi), and temakizushi (hand roll).
The term sashimi is closer in definition to “raw fish”, but sashimi can also refer to any uncooked meat or vegetable. (Wiki)
