IPA: /dɪˈɡriːsər/
KK: /dɪˈɡriːsər/
A substance or machine used to remove grease and oil from surfaces or mechanical parts.
The mechanic used a degreaser to clean the engine before repairs.
Degreaser → It is formed from "de-" (meaning down or away) and "grease" (from Old French *graisse*, meaning fatty substance) and the suffix "-er" (meaning a person or thing that performs an action). The word "degreaser" refers to a substance or tool that removes grease or fatty substances.
Think of something that works 'down' ('de-') to remove 'grease' — that's why a degreaser is used to eliminate greasy substances.
