Etymology

熱 combines 埶 (a phonetic component with a sense of planting or setting) and 灬 (fire), suggesting heat or warmth. The modern form is consistent with this phono-semantic structure.

Meaning mnemonic

The top part 埶 looks like a person kneeling over a mound of earth, and the bottom 灬 is fire. Imagine someone tending a fire, feeling the intense heat rise—enough to cause a fever or passionate excitement.

Reading mnemonic

For ネツ, picture a net catching all the heat from the fire: net -> ネツ, and the net traps the intense warmth.
