1. air=Old Irish ar, air, ante, propter, Welsh ar, er, Breton er, Gaul are-, Celtic ari, arei, Greek $$G pará, $$G paraí, by, before; Latin prae; English fore, for. This prep. aspirates in Irish, and in Gaelic idioms it still does so, e.g. air chionn. 2. link=air.1air=Old Irish for, "super", Old Welsh and Old Breton guor, Breton voar, oar, Gaulish ver-; Greek $$Gu$$`pér; Latin s-uper; English over. This prep. did not aspirate; it ended originally in r in Gaelic; as an inseperable prefix ( vero-, viro- in Gaulish) it aspirated, as in the modern form of old names like Fergus, now Fearghuis or Fear'uis (gen. case). 3. link=air.2air=Old Irish iar n-, after, pre-Celtic epron; Sanskrit aparám, afterwards, aparena, after; Gothic afar, after, English af-ter. Further come Greek $$Go$$'pi-, behind, e$$'pí-, to, Latin ob-, op-. See iar. This is the prep. that is used with the inf. to represent a perfect or past participle in Gaelic - Tha mi air bualadh; "I have struck". </LI></OL>
