IPA: /jʊərˈsɛlf/
KK: /jɚˈsɛlf/
A word used to refer to the person being addressed, often for emphasis or to indicate that the action is done by that person.
You should take care of yourself and get some rest.
Yourself → The word is formed from "your" (from Old English "eower", meaning belonging to you) and "self" (from Old English "seolf", meaning oneself). The term "yourself" refers to the person that belongs to you, emphasizing one's own identity.
Think of 'your' as belonging to you and 'self' as oneself — together, they remind you that 'yourself' means your own identity.
