aegis

Pronunciation

• IPA: /ˈiːd͡ʒɪs/^[1]

Etymology

It is borrowed from Latin aegis,^[2][3][4][5] from Ancient Greek αἰγίς (aigís, “the shield of Zeus”),^[2][6][3][4] probably from Ancient Greek αἴξ (aíx, “goat”) (stem aig-),^[2][6][4][5] since the shield was made of goatskin.^[6][5] The Greek goat word comes from Proto-Indo-European *aig- “goat”.^[6]

Earliest recorded meaning

The shield of Zeus or Athena, or of their Roman counterparts Jupiter and Minerva (1581 in Merriam-Webster; 1611 in Barnhart).^[4][2][1]

Semantic evolution

In myth the aegis was a protective attribute, Athena's being a goatskin cloak set with a Gorgon's head;^[6][3][5] so to be under someone's aegis came to mean being under their protection.^[2][6] The figurative sense is first recorded in 1793.^[2][6] In the 20th century the meaning widened to sponsorship or patronage, as in under the aegis of the museum.^[3][4][5]
