Etymology
恒 combines 忄 (heart) with 亘, which likely contributes the sound and the idea of spanning or extending, suggesting a heart that remains steady over time.
Meaning mnemonic
The heart radical 忄 beside 亘 (which looks like a stretched sun 日 with a line above and below) suggests a heart that stays constant like the sun's daily arc.
Reading mnemonic
For コウ, imagine a constant, unwavering heart that beats with a steady 'koh' sound: koh -> コウ, always the same rhythm.
