Word History

Etymology

borrowed from New Latin branchiālis, from Latin branchia "gills" (borrowed from Greek bránchia, of uncertain origin) + -ālis -al entry 1

Note: Greek bránchia is conventionally taken to be from the base of bránchos "hoarseness, sore throat" (as by Frisk, Griechisches Etymologisches Wörterbuch), though the semantic connection is not entirely self-evident, and bránchos is in its turn linked with brónchos "windpipe, throat," though there is no explanation for the change in vowel. If the glosses brachṓdēs: trachýs ("rough, harsh") and brakías: tracheîs tópous ("rough places") in the lexicon of the Greek grammarian Hesychius are relevant, the set of alternations brak-/brach-/branch- suggests pre-Greek substratum (see E. Furnée, Die wichtigsten Konsonantischen Erscheinungen des Vorgriechischen [Mouton, 1972], pp. 128, 276). In the case of all these words both form and meaning may be affected by folk etymology.
