IPA: /ɪˈroʊdənt/
KK: /ɪˈroʊdənt/
A thing that causes erosion or wears away material over time.
The river acted as an erodent, gradually shaping the landscape.
Erodent is derived from the Latin root "erodere" (meaning to gnaw away) and the suffix "-ent" (indicating an agent or something that performs an action). The word describes something that gnaws away or erodes.
Think of something that 'gnaws away' ('erodere') — that's why erodent refers to something that erodes.
