Uncurious → It is formed from "un-" (meaning not) and "curious" (from Latin "curiosus", meaning eager to know or inquisitive). The word "uncurious" means not eager to know or lacking curiosity.
Think of 'not' ('un-') being added to 'eager to know' ('curious') — that's why 'uncurious' means lacking curiosity.
