Instate is formed from "in-" (meaning into) and "statuere" (meaning to set or place). The word means to set or place someone into a position or office.
Think of 'putting someone into' a position ('in-') and 'setting' them there ('statuere'). This helps you remember that instate means to place someone into a role.
