NOTE: For an association between something projecting and a corvid cf. the etymology of corbel entry 1. Italian cornice has also been seen as an outcome of Greek korōnid-, korōnís "crook-beaked, curved, curved pen stroke, copestone (in the lexicographer Hesychius)," though phonologically this is implausible. The base *kor-/*ḱor- is ultimately onomatopoeic, perhaps an expansion of *kr-, the initial of other independently derived Indo-European words for corvid birds (cf. crow entry 1, raven entry 1).
