oneself

The word "oneself" combines "one," derived from Old English "ān" (meaning "a single person or thing"), with "self," from Old English "self" (referring to identity or essence). This compound emerged in Middle English to emphasize reflexive or intensive actions, mirroring structures like "myself" or "yourself." The logic reflects a grammatical need to unify the concept of an individual ("one") with reflexive/emphatic pronouns ("self").
