IPA: /ɪnˈvɒl.jʊ.kreɪt/
KK: /ɪnˈvɑlʊˌkreɪt/
Describing something that has a protective covering or envelope, often used in botanical contexts.
The plant's flowers were surrounded by an involucrate structure that provided support.
Involucrate → It is formed from "in-" (meaning in or within) and "volucris" (from Latin, meaning winged or flying). The word describes something that is enveloped or covered, as if being wrapped within wings.
Think of something being 'wrapped within' ('in-') like a bird's wings ('volucris') — that's why involucrate means to be enveloped.
