Erglis, Prussian. areli, pragerm. *arōn~arnuz~arnaz (from where did the Gothic ara, OE earn OE German aro, arn, OE north orn)[4], Proto-Celtic. *eriro- (from where Middle-Irl. irar, Middle-Wall. eryr, Middle Breton - erer, Cornish and Breton - er) [5], Hittite - haraš, [6]. All these words, as well as other Greek. ὄρνῑς bird and Arm. or kite, seagull and Arm. artsiv eagle goes back to the Indo-European root *Hor-/Her-, (ar, er). The Indo-European eagle has a cult sensibility[7][8]. In Latin, there was a taboo-motivated replacement of the Indo-European name for the eagle with the word aquila, associated with aqua water[9].
