IPA: //ˈɡreɪndʒər//
KK: /ˈɡreɪndʒər/
A person who is a member of a Grange, which is an organization for farmers and their families, or simply a farmer, especially in the Northeastern and Upper Midwest regions of the United States.
The granger attended the meeting to discuss agricultural issues affecting the community.
Granger originates from Old French 'grangier' (meaning granary or barn keeper), which itself comes from 'grange' (meaning barn). The term refers to a person who manages or works in a granary or barn, particularly in agricultural contexts.
Think of someone who takes care of a 'granary' ('grange') — that's why a granger is someone who manages a barn or granary.
