IPA: //ˈraɪpənər//
KK: /ˈraɪpənər/
A substance that helps fruits or vegetables to become ripe or mature.
Farmers often use a ripener to ensure their crops are ready for harvest.
Ripener → It is formed from "ripe" (from Old English *rīpe*, meaning fully matured or ready for harvest) and "-ner" (a suffix used to indicate a person or thing that performs a specific action). The word "ripener" refers to something or someone that causes or facilitates ripening.
Think of something that helps make things 'ready' or 'mature' — 'ripe' means fully matured, and '-ner' indicates a person or thing that does something.
