IPA: /dɪˈkæntər/
KK: /dɪˈkæntər/
A container, often made of glass, used to hold and serve wine or other liquids, typically designed to enhance the presentation of the drink.
She poured the wine into the decanter to let it breathe before serving.
Decanter → It is formed from "de-" (meaning down or away) and "canthare" (from Latin, meaning a drinking vessel). The word describes a vessel used to pour wine or other liquids down from one container to another, typically to separate sediment or aerate the liquid.
Think of pouring liquid 'down' ('de-') from a 'vessel' ('canthare') — that's what a decanter does.
