Coronet is from Old French 'coronete', a diminutive of 'corone' ('crown'), from Latin 'corona' ('crown, garland'). The ancestry passes through Old French coronete and Latin corona. In present use as a noun, it means "a small crown worn by nobility below the rank of sovereign", keeping the historical formation close to the word's ordinary semantic work.
