chae·​ta ˈkē-tə How to pronounce chaeta (audio)
plural chaetae ˈkē-ˌtē How to pronounce chaeta (audio)
chaetal adjective

Word History


borrowed from Greek chaítē "growth of hair, flowing locks, mane of a horse," going back to Indo-European *ghai̯t- "growth of hair," whence also, from a presumed s-stem *ghai̯tes-, Middle Irish gaísid "coarse stubbly hair, bristles," gaísitech "coarse-haired, bristly," Avestan gaēsa- "curly hair," gaēsu- "curly-haired"

Note: A reconstruction *ghai̯t- is unsatisfactory for those who reject the possibility of Indo-European *a and would require a mechanical reconstruction with a laryngeal, as *gheh2it- or *ghh2ei̯t-.
