Oneself → The word is formed from "one" (from Old English "ān", meaning a single unit) and "self" (from Old English "seolf", meaning oneself or the same person). The term "oneself" refers to the individual as a single entity or the same person.
Think of 'one' as a single unit and 'self' as referring to you — together, they remind you that 'oneself' means you as an individual.
