Unsettle → It is formed from "un-" (meaning not) and "settle" (from Old English "setlan", meaning to place or establish). The word "unsettle" means to disturb or disrupt something that has been established or placed.
Think of 'not' being added to 'settle' — this helps you remember that 'unsettle' means to disturb something that was once stable.
