The process of removing the outer layer or covering from something, such as bark from a tree or the outer layer of an organ in surgery.
The decortication of the seed is necessary to prepare it for planting.
Decortication is formed from "de-" (meaning away from) and "cortex" (from Latin, meaning bark or outer layer). The term refers to the process of removing the outer layer or bark from something, such as a plant or fruit.
Think of 'removing the outer layer' — 'de-' means away from, and 'cortex' refers to the outer layer or bark.
