Etymology

The word lawful originates from Old English lagu (meaning "rule" or "ordinance"), which itself derives from Old Norse lag, meaning "something laid down or fixed." The suffix -ful (from Old English -full) transforms the noun law into an adjective, conveying the sense of "full of law" or "in accordance with law." Over time, lawful evolved to encompass both legal compliance and moral legitimacy, reflecting societal values tied to justice and order.
