Annuit CoeptisyoudaoicibaDictYouDict[Annuit Coeptis 词源字典]
on the Great Seal of the United States of America, condensed by Charles Thompson, designer of the seal in its final form, from Latin Juppiter omnipotes, audacibus annue coeptis "All-powerful Jupiter favor (my) daring undertakings," line 625 of book IX of Virgil's "Aeneid." The words also appear in Virgil's "Georgics," book I, line 40: Da facilem cursam, atque audacibus annue coeptis "Give (me) an easy course, and favor (my) daring undertakings." Thompson changed the imperative annue to annuit, the third person singular form of the same verb in either the present tense or the perfect tense. The motto also lacks a subject.

The motto is often translated as "He (God) is favorable to our undertakings," but this is not the only possible translation. Thomson wrote: "The pyramid signifies Strength and Duration: The Eye over it & Motto allude to the many signal interpositions of providence in favour of the American cause." The original design (by William Barton) showed the pyramid and the motto Deo Favente Perennis "God favoring through the years."[Annuit Coeptis etymology, Annuit Coeptis origin, 英语词源]

"A mythical creature that resembles a seal in the water but assumes human form on land", From selch, variant of seal1, + -ie. More seal from Old English:Rather than signing their name, people formerly stamped a personal seal in wax on a completed letter or other document. The expressions put the seal on, ‘to put the finishing touch to something’, and set your seal to, ‘to mark something with your own distinctive character’, both derive from this. To seal something off reflects the use of seals to check that something has not been opened or disturbed. In these and related uses, seal goes back to Latin sigillum ‘small picture’, from signum ‘a sign’, the source of design (late 16th century), designate (mid 17th century), ensign (Late Middle English), insignia (mid 17th century), sign (Middle English), signal (Late Middle English), scarlet, and numerous other English words. This seal dates from Middle English. The name of the animal seal derives from Old English seolh, the source also of the selkie or silkie (mid 16th century), the mysterious seal woman of folklore.
