Root Explanation

Thermonuclear → It is formed from "thermo-" (from Greek "thermos", meaning heat) and "nuclear" (from Latin "nucleus", meaning kernel or core). The word "thermonuclear" refers to reactions or processes that occur at extremely high temperatures, involving the core or nucleus of atoms.

Memory Tip

Think of 'heat' ('thermo-') being involved in reactions at the 'core' ('nuclear') of atoms — that's what thermonuclear means.
