Word origin
Formed from Middle English ayenes, agenes, againes (“in opposition to”), a southern variant of agen, or directly from again, either way with adverbial genitive singular ending -es; the parasitic -t was added circa 1350, probably by confusion with the superlative ending -est. By surface analysis, again + -st (excrescent ending).
