ethical
UK: ˈeθɪk(ə)l | US: ˈeθɪk(ə)l
adj. relating to moral principles or the branch of knowledge dealing with these principles
adj. morally correct or acceptable
The word "ethical" derives from the Greek "ethikos," meaning "pertaining to character or morals," which itself comes from "ethos" (custom, habit, or character). The suffix "-al" (from Latin "-alis") transforms the noun into an adjective, giving "ethical" its modern meaning of "relating to moral principles." The evolution reflects a shift from describing societal customs ("ethos") to individual or systemic morality ("ethics").
