ambient (adj.)[ambient 词源字典]: 1590s, "surrounding, encircling," from Latin ambientem (nominative ambiens) "going round," present participle of ambire "to go around," from amb- "around" (see ambi-) + ire "go" (see ion). The ground sense of "revolving" led to "encircling, lying all around."[ambient etymology, ambient origin, 英语词源]
amphitheater (n.): late 14c., from Latin amphitheatrum, from Greek amphitheatron "double theater, amphitheater," neuter of amphitheatros "with spectators all around," from amphi- "on both sides" (see amphi-) + theatron "theater" (see theater). Classical theaters were semi-circles, thus two together made an amphi-theater.
circum-: word-forming element meaning "around, all around, on all sides," from Latin circum- a common element in word-formation, from adverb and preposition circum "around, round about," literally "in a circle," probably accusative form of circus "ring" (see circus). In French, the element became circon-; Kitchin points out that con for cum is common even in classical Latin.
Pericles: Athenian statesman (c. 495-429 B.C.E.), from Greek Perikles, literally "far-famed," from peri "all around" (see peri-) + -kles "fame" (see Damocles). His leadership of Athens marks its intellectual and material zenith. Related: Periclean.
pumpkin (n.): 1640s, alteration of pompone, pumpion "melon, pumpkin" (1540s), from Middle French pompon, from Latin peponem (nominative pepo) "melon," from Greek pepon "melon," probably originally "cooked (by the sun)," hence "ripe;" from peptein "to cook" (see cook (n.)). Pumpkin-pie is recorded from 1650s. Pumpkin-head, American English colloquial for "person with hair cut short all around" is recorded from 1781. Vulgar American English alternative spelling punkin attested by 1806.
America's a dandy place:
The people are all brothers:
And when one's got a punkin pye,
He shares it with the others.

[from "A Song for the Fourth of July, 1806," in "The Port Folio," Philadelphia, Aug. 30, 1806]
