limey

the word "limey" originated in the late 19th century as american and australian slang for a british sailor, and later for british people in general. its logic is directly historical: the british royal navy, from the mid-18th century onward, issued regular rations of lime juice to sailors to prevent scurvy, a practice that distinguished them from other navies. the suffix "-y" was added to form an adjective meaning "associated with limes," which then became a noun. thus, the term evolved from a literal reference to a dietary practice into a national stereotype and colloquial identifier.

Structure: lime (citrus fruit) + y (adjective-forming suffix) lime (from english 'lime', the citrus fruit, of persian origin via arabic and french); y (a native english suffix forming adjectives meaning "characterized by or full of").
