Meaning

灰 centers on the powdery remains left after fire: ashes. The cremation sense is a specific application of burning to ashes, while "puckery juice" is an obscure, likely archaic meaning that does not fit the main conceptual center.

Etymology

灰 combines 火 (fire) with a reduced form of 厂 (cliff), suggesting the remains of a fire under a cliff or shelter. The exact historical development is uncertain, but the association with fire and residue is clear.

Meaning mnemonic

Picture a cliff (厂) sheltering the remains of a fire (火): the gray, powdery ashes left behind. That's 灰.

Reading mnemonic

For カイ, imagine a pile of ashes turning into a kite (カイト) and flying away: kite -> カイ, and the ashes scatter like a kite in the wind.
