Unmoor → It is formed from "un-" (meaning not or to reverse) and "moor" (from Old English *morian*, meaning to secure a ship by anchoring). The word "unmoor" means to release a ship from its mooring or to set it free from being secured.
Think of 'un-' meaning to reverse or not, and 'moor' meaning to secure a ship. So, unmoor means to set a ship free from being secured.
