O.E. æt, common P.Gmc. (cf. O.N., Goth. at, O.Fris. et, O.H.G. az), from PIE *ad- "to, near, at" (cf. L. ad "to, toward" Skt. adhi "near"). Lost in Ger. and Du., which use their equivalent of to; in Scand., however, to has been lost and at fills its place. At-home (n.) "reception of visitors" is from 1745; baseball at-bat "player's turn at the plate" is from 1941.

See At.] As a prefix ad- assumes the forms ac-, af-, ag-, al-, an-, ap-, ar-, as-, at-, assimilating the d with the first letter of the word to which ad- is prefixed.

Examples: adduce, adhere, adjacent, admit, advent, accord, affect, aggregate, allude, annex, appear, etc. It becomes ac- before qu, as in acquiesce.
