word-forming element meaning "both, on both sides," from Latin ambi- "around, round about," from PIE *ambhi "around" (cognates: Greek amphi "round about;" Sanskrit abhitah "on both sides," abhi "toward, to;" Avestan aibi; Old English ymbe, German um; Gaulish ambi-, Old Irish imb- "round about, about;" Old Church Slavonic oba; Lithuanian abu "both"). The PIE root probably is an ablative plural of *ant-bhi "from both sides," from *ant- "front, forehead" (see ante).[ambi- etymology, ambi- origin, 英语词源]
