Biologists explore the effects of ambient light on plants; acoustics experts try to control ambient sound; and meteorologists monitor the temperature of ambient air. All this can make ambient seem like a technical term, but when it first saw light of day, that all-encompassing adjective was as likely to be used in poetry as in science, as when Alexander Pope wrote of a mountain “whose tow’ring summit ambient clouds conceal’d.” Both poets and scientists use ambient today to describe things that surround—that is, exist on all sides of—someone or something. And by “all” we mean all. One would not likely describe someone sitting in the middle of their lawn as being amid “ambient grass,” for example. Ambient, which comes from the Latin verb ambīre meaning “to surround, encircle, or embrace,” most often describes things—such as noise or humidity—that are all around someone, from top to bottom.

Word History

Etymology

Adjective

borrowed from Latin ambient-, ambiens, present participle of ambiō, ambīre "to visit in rotation, solicit (political support), seek to obtain, surround, encircle, embrace," from amb- "around, on both sides" + eō, īre "to go"; amb- going back to Indo-European *h₂m̥b^hi "around," whence also Germanic *umbi- (whence Old English ymbe "around, about," Old Frisian umbe, Old Saxon & Old High German umbi "around, about, concerning," Old Icelandic um, umb "around, about, beyond, over"), Gaulish ambi- "around (in names)," Old Irish imb, imm "around, about," Welsh & Breton am, Greek amphí "about, on both sides of," Armenian amb- (in ambołǰ "whole, intact"), Old Avestan aibī "for," Old Persian abiy "to, toward," Sanskrit abhí — more at issue entry 1

Note: The Latin prefix amb- is peculiar in that the expected linking vowel -i- never occurs; before consonants it syncopates, with consequent assimilation: -b- drops, and -m- becomes -n- before non-labial sounds (see amplexus, amputate, ancilla, anfractuous). Indo-European *h₂m̥b^hi may have developed from *h²n̥t-b^hi, a frozen instrumental plural form of the noun *h²ent- "front, face" (see ante-). The same noun figures in *h₂(e)nt-b^hoh₁ "both" (see ambi-).
