You will almost always meet this word in one set phrase: under the aegis of someone. It means that person or group is protecting you, backing you, or letting you work under their name.
You你 will almost always幾乎總是 in one set phrase在一個固定片語裡 meet this word遇到這個詞：under the aegis of someone「under the aegis of someone」（在某人的庇護下）。It它 means意思是 that person or group那個人或團體 is protecting you, backing you, or letting you work under their name正在保護你、支持你、或讓你掛他們的名號做事。
A science fair under the aegis of the university is not merely happening near the university — the university is standing behind it.
A science fair一場科展 under the aegis of the university在這所大學的庇護下 is not merely happening near the university並不只是辦在大學附近而已 — the university這所大學 is standing behind it是在背後撐著它。
The word feels official, a little dressed-up; newspapers, universities, and formal notices like it. In ordinary talk people say with the support of or backed by, and they sound more like themselves.
The word這個詞 feels聽起來 official很官方，a little dressed-up有點裝腔作勢；newspapers, universities, and formal notices報紙、大學、和正式公告 like it都愛用。In ordinary talk在日常對話裡 people人們 say會說 with the support of或backed by「with the support of」或「backed by」，and而 they這樣講 sound more like themselves聽起來更像他們自己會講的話。
Though actually, the tidy modern meaning (support, sponsorship) is already a stretch from the old story. In Greek myth the aegis was a goatskin shield, the one the goddess carried. English kept the idea of a shield in front of you and mostly dropped the goat.
Though actually不過其實，from the old story跟原本的老故事相比，the tidy modern meaning這個現在整潔的意思（support, sponsorship支持、贊助） is already a stretch已經差很遠了。In Greek myth在希臘神話裡 the aegis「aegis」這個東西 was是 a goatskin shield一面山羊皮做的盾牌，the one就是 the goddess Athena carried女神雅典娜帶著的那面。English英文 kept保留了 the idea of a shield in front of you一面擋在你前面的盾牌這個概念，and而 mostly dropped the goat大致上把山羊的部分丟掉了。
You rarely hear the word outside that under the aegis of pattern.
outside that under the aegis of pattern除了在「under the aegis of」這個句型之外，You你 rarely很少 hear the word聽到這個詞。
組成English borrowed the whole word from Latin aegis, which had borrowed it from Greek aigís — first a goatskin, then the shield of Athena. The Greek word for goat is probably hiding in the first part. It does not split into English pieces.

aegisnoun/ˈiːd͡ʒɪs/

human-sciencesmysticismmythologyA 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.
- 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.
- Herodotus, as proof of this origin of Minerva, says, that the Greeks had taken from the Libyan women, the dress and the ægis with which her statues were represented: this dress was of leather: the ægis, as its name implies, was simply a goatskin died red and worn over the shoulders like a mantle: the extremity of it was cut into shreds or tassels, which the lively fancy of the Grecian artists converted into serpents.

Guidance, protection; endorsement, sponsorship.
- under the aegis
- [T]hree ex-Secretaries of State for War had learnt their military theory under the ægis of Regular soldiers. Now it is an admitted fact that, broad-minded and enterprising as soldiers have frequently proved themselves in matters unconnected with the actual corporate body to which they belong, they are, nevertheless, perhaps the most obstinate and optimistic advocates of a laissez-faire policy, which the interests of their own profession are at issue, that it is at all possible to conceive.
