IPA: /ˌɛks.juˈdeɪ.ʃən/
KK: /ɛksjuˈdeɪʃən/
The process of a substance slowly coming out or leaking from a surface, often in a liquid form.
The exudation of sap from the tree indicated that it was healthy.
Exudation → It is formed from "ex-" (meaning out of) and "udare" (meaning to sweat or ooze). The word describes the process of a substance oozing or being released out of something, often in a liquid form.
Think of something 'oozing out' ('ex-') like sweat ('udare') — that's why exudation refers to the process of a substance being released.
