splash, suds
沫 centers on liquid bursting into small, light particles: a splash of water or the frothy suds that form on its surface.
沫 combines 氵 (water) with 末, which likely contributes the sound and the idea of something small or scattered, together suggesting water splashing into fine droplets or foam.
Water 氵 plus the scattered shape of 末 (like the tip of a branch) gives the image of water breaking into tiny splashes and suds.
For マツ, picture a splash of water hitting a mat and foaming up: mat -> マツ, and the suds soak into the mat.
