From Middle English supposen, borrowed from Old French supposer, equivalent to prefix sub- (“under”) + poser (“to place”); corresponding in meaning to Latin supponere (“to put under, to substitute, falsify, counterfeit”), suppositum. See pose.
The verb is transitive and often takes a 'that' clause or an infinitive. When used in the passive 'be supposed to', it expresses duty or a widely held belief.
