Etymology
砑 combines 石 (stone) with 牙, which likely contributes the sound. The stone radical suggests a stone tool used for grinding or polishing.
Meaning mnemonic
A stone 石 roller with tooth-like 牙 projections grinds and polishes the surface as it rolls.
Reading mnemonic
For ガ, imagine the grinding stone making a harsh 'ga-ga-ga' sound as it rolls over the surface: ga -> ガ.
