IPA: /dɪˌfoʊliˈeɪʃən/
KK: /dɪˌfoʊliˈeɪʃən/
The process of leaves falling off a plant or tree, usually when they are mature or during certain seasons.
Defoliation can occur naturally in autumn when trees lose their leaves.
Defoliation is formed from "de-" (meaning down or away) and "folium" (meaning leaf). The word describes the process of removing leaves from a plant or tree, effectively taking them away.
Think of 'taking leaves away' — 'de-' means down or away, and 'folium' means leaf, which helps you remember that defoliation is the removal of leaves.
