Etymology
凸 is a pictograph of a shape with a raised middle, directly representing the idea of convexity or protrusion.
Meaning mnemonic
The central vertical stroke pushes up past the top border, like a bump on a surface. 凸 is anything convex or sticking out unevenly.
Reading mnemonic
For トツ, imagine a toe sticking out from a flat surface, making it uneven: toe -> トツ, and the bump is convex.
