A type of salt that comes from ascorbic acid, which is commonly known as vitamin C.
Sodium ascorbate is often used as a dietary supplement to provide vitamin C.
Ascorbate is formed from "a-" (meaning without) and "scorbutus" (Latin for scurvy). The term refers to a substance that prevents or counteracts scurvy, which is a disease caused by a deficiency of vitamin C.
Think of 'without' ('a-') scurvy ('scorbutus') — that's why ascorbate is related to preventing scurvy.
