IPA: /ɪˈrʌmpənt/
KK: /ɪˈrʌmpənt/
Describing something that is breaking through a surface or covering, often in a forceful or sudden way.
The erumpent plant pushed its way through the soil, reaching for the sunlight.
Erumpent is formed from "e-" (meaning out) and "rumpere" (meaning to break). The word describes something that breaks out or bursts forth.
Think of something 'breaking out' ('rumpere' means to break and 'e-' means out) — that's why erumpent refers to something that bursts forth.
