This entry combines structured lexical data with WordToolSet review checks. Definitions, examples, synonyms, and usage notes may come from different source tables, so the page is designed to show evidence from more than one angle before you rely on "aegis" in a final draft.
If a word has several senses, prefer the sense that matches your sentence's grammar and surrounding context. A correct definition can still be the wrong choice when the sentence needs a different register, emphasis, or level of specificity.
Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "aegis" as the right word for your sentence.
If your draft is formal, technical, persuasive, or sensitive, compare "aegis" with a nearby alternative so the final choice matches both meaning and reader expectation.
Check whether "aegis" is acting as name, noun in your sentence. A definition is only useful when the grammar matches the way the word is being used.
Compare it with "protection" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.
Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.
Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.
Before publishing a sentence with "aegis", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.
When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.
"The goat Amalthea, which had suckled Jove, being dead, that god is said to have covered his buckler with the skin thereof, whence the appellation Aegis, from αιξ, αιγις, a she-goat. Jupiter afterwards restoring the goat to life, covered it with a new skin, and placed it among the stars. This buckler, which was the work of Vulcan, he gave to Minerva, who having killed the Gorgon Medusa, nailed her head to the middle of the Aegis, which henceforth possessed the faculty of converting to stone all who beheld it, as Medusa herself had while alive."
"under the aegis"
"The Aegis collision - why couldn't it have been avoided?"
A mythological shield associated with the Greek deities Zeus and Athena (and their Roman counterparts Jupiter and Minerva) shown as a short cloak made of goatskin worn on the shoulders, more as an emblem of power and protection than a military shield. The aegis of Athena or Minerva is usually shown with a border of snakes and with the head of Medusa in the center.
Common synonyms include: protection, abetment, advocacy, arm guard, armament, armor.
The Aegis collision - why couldn't it have been avoided?
Pronounced /ˈiːd͡ʒɪs/.
Borrowed from Latin aegis, from Ancient Greek αἰγίς (aigís, “goatskin; shield of Athena”), probably from αἴξ (aíx, “goat”), from Proto-Indo-European *h₂eyǵ- (“goat”). The plural form aegides (/ˈiːd͡ʒɪdiːz/) is borrowed from Latin aegides, from Ancient Greek αἰγῐ́δες (aigĭ́des).
