His unloving words hurt her feelings deeply.
Unloving → It is formed from "un-" (meaning not) and "loving" (from the root "love" which comes from Old English "lufu", meaning deep affection or strong attachment). The word "unloving" means not showing love or affection.
Think of 'not' ('un-') showing 'affection' ('loving') — that's why unloving means lacking love.
