laryngeal adj.

"cartilaginous cavity in the upper windpipe where vocal sounds are made," 1570s, from French larynx (16c.), via medical Latin, from Greek larynx (genitive laryngos) "the upper windpipe," which is probably from laimos "throat" (a word of uncertain etymology) but influenced by pharynx "throat, windpipe" (see pharynx).
