Pronunciation: es-kyuh-luhnt (listen to it on m-w.com)

Adjective: edible; Noun: something that is edible

Etymology: 17th century. From the Latin esculentus (edible)

Usage: For example, esculent roots or mushrooms.

Taste, defined by the early-nineteenth-century French gastronome Brillat-Savarin as that sense "by means of which we approve the sapidity [tastiness] and esculence [edibility] of things," is in fact physiologically bound up with smell and with touch.
