History
Etymology
From Middle English resoun, reson, from Anglo-Norman raisun (Old French raison), from Latin ratiō, from ratus, past participle of reor (“reckon”), ultimately from Proto-Indo-European *h2reh1- (“to think”), reanalysed root of *h2er- (“to put together”). Displaced native Middle English reden (found in compounds), from Old English rǣden (“condition, stipulation, calculation, direction”), from the same Proto-Indo-European source (compare West Frisian reden (“reason”), Dutch reden (“reason”)). Doublet of ration and ratio.
From Middle English reason, reson, resen, rasen, from Old English ræsn (“beam, rafter, ceiling, wall panel”), probably from Proto-West Germanic *raʀn (“house”), from Proto-Germanic *razną (“house, dwelling”), from Proto-Indo-European *h1erh1- (“to rest”).
