The Hebrew and Greek that is translated as “widow” in English is translated in West Kewa as ona wasa or “woman shadow.” (Source: Karl J. Franklin in Notes on Translation 70/1978, pp. 13ff.)

The etymological meaning of the Hebrew almanah (אַלְמָנָה) is likely “pain, ache,” the Greek chéra (χήρα) is likely “to leave behind,” “abandon,” and the English widow (as well as related terms in languages such as Dutch, German, Sanskrit, Welsh, or Persian) is “to separate,” “divide” (source: Wiktionary).
