A small container or dish used to hold and serve salt, typically found on dining tables.
Please pass the saltcellar so I can season my food.
Saltcellar → The word is formed from "salt" (from Old English *sealt*, meaning a mineral substance used for seasoning) and "cellar" (from Old French *celier*, meaning a storeroom or place for storage). A saltcellar is a container or holder for salt, typically used at the dining table.
Think of a 'storeroom' ('cellar') for 'salt' — that's what a saltcellar is, a place to keep salt.
