borrowed from New Latin, going back to Late Latin, "trachea, throat," borrowed from Greek brónchos, of uncertain origin
Note: Greek brónchos has been linked with *bróchō "gulp down" (attested only in the aorist bróxai) and bróchthos "throatful, draft," though the nasal is not explicable by Indo-European-based rules. Traditionally (e.g., Pokorny, Indogermanisches etymologisches Wörterbuch, p. 246; Frisk, Griechisches etymologisches Wörterbuch, 1:270) this set of words is assigned to the o-grade of an Indo-European base *gwregh-, whence Middle High German krage "neck, throat, collar," Middle English crawe "crop of a bird" (from Old English *cræga; see craw), and, from a lengthened grade, Old Irish bráge "neck, throat, gullet" (genitive brágat, from a stem *brágant-), Welsh breuant "throat, larynx" (cf. Old Welsh abalbrouannou "Adam's apple"). More recently, R. Beekes, Etymological Dictionary of Greek, s.v. bróxai (following Edzard Furnée, Die wichtigsten konsonantischen Erscheinungen des Vorgriechischen, p. 276) treats this set as pre-Greek substratal words, which would account for the nasal in brónchos as well the deviant a in the presumably related word bránchos "hoarseness, sore throat" (see the note at branchial).
