Upstand → The word is formed from "up" (meaning in a higher position) and "stand" (from Old English "standan", meaning to be in an upright position). The term "upstand" refers to the act of standing up or being in an upright position.
Think of being in a higher position ('up') and 'standing' — that's why upstand means to stand up.
