rankle: [14] Etymologically, if something rankles, it festers from the effects of a ‘dragon’s’ bite. Nowadays the word is only used metaphorically, but it originally meant literally ‘be sore, fester’. It was borrowed from Old French rancler, a variant of draoncler. This was derived from draoncle ‘ulcer’, which in turn came from dranculus, the medieval Latin descendant of dracunculus, a diminutive form of Latin dracō ‘snake’ (source of English dragon). The notion underlying the word is of an ulcer caused by the bite of a snake.
