這個詞的起源不確定,可能是來自古法語 rascler 的減小形式,源自通俗拉丁語 *rasicare “刮”,(參見 rash(n.)),意爲“刮削物”。 “[U]sed in objurgation with much latitude, and often, like rogue, with slight meaning” [Century Dictionary]. 在中古英語中,也用於形容因某些特質而不適合追逐的動物,尤其是瘦鹿。也曾是一個形容詞。
Roughly, the word in -ity usually means the quality of being what the adjective describes, or concretely an instance of the quality, or collectively all the instances; & the word in -ism means the disposition, or collectively all those who feel it. [Fowler]
