Root Explanation

Unilluminating → It is formed from "un-" (meaning not) and "illuminating" (from Latin "illuminare", meaning to light up or make clear). The word "unilluminating" means not making something clear or not providing insight.

Memory Tip

Think of 'not' ('un-') providing 'light' or clarity ('illuminating') — that's why unilluminating means something that does not shed light on a subject.
