Etymology
窒 combines 穴 (hole, cavity) with 至, which likely contributes the sound. The idea is a hole being stopped up or blocked.
Meaning mnemonic
A hole (穴) is stopped up when something reaches (至) it and blocks the opening. Picture a cork reaching a bottle's hole and plugging it tightly.
Reading mnemonic
For チツ, imagine a blocked pipe that finally clears with a sharp 'cheats!' sound as the obstruction is forced out: cheats -> チツ.
