reasonably
UK: ˈriːz(ə)nəbli | US: ˈriːz(ə)nəbli
adv. in a sensible or logical manner
adv. to a moderate or acceptable degree
The word "reasonably" combines "reason" (from Old French raison, meaning "logic" or "judgment") with the suffix "-able" (indicating capability, from Latin -abilis), and the adverbial suffix "-ly" (from Old English -lice). The progression reflects the idea of acting with logic ("reason") in a manner that is achievable ("-able") and characterized by ("-ly") moderation or sensibility.
