Pronunciation

  • Classical: [a.kʷɪˈliː.nʊs][1]
  • Ecclesiastical: [a.kʷiˈliː.nus][1]

Forms

aquilīnus (feminine aquilīna, neuter aquilīnum); first/second-declension adjective[1]

Etymology

It is formed from Latin aquila (“eagle”) + -īnus.[2][1]

Earliest recorded meaning

Plautus uses it in the Pseudolus, of cooks with claws like a kite's or an eagle's.[2][3][4]

Semantic evolution

It meant like an eagle's, or an eagle's.[2] Apuleius describes eyes flashing in a gaze that is “quite aquiline”, so that the word implied sharp sight,[3][5] and Tertullian speaks of the Babylonian king's eagle-like nails.[3] The grammarian Priscian cites it as the adjective of aquila.[3] Aquilinus was also a Roman personal name.[3]

Medieval writers kept the sense “eagle-like”, also in allegory of John the Evangelist,[6] and through association with aquilus it also meant dark or swarthy.[6] At Oxford, Aula Aquilina was Eagle Hall.[7] English aquiline, first of hooked noses, comes from it.[8]
