drown, sink, hide, fall into, disappear, die
没 centers on something disappearing beneath a surface or boundary: sinking into water, drowning, vanishing from sight, or metaphorically falling into a state. The idea of dying extends naturally from disappearing completely.
没 combines 氵 (water) with 殳, which likely contributes the sound. The character originally expressed sinking or disappearing into water.
Water 氵 on the left and a shape like a hand holding a tool 殳 on the right: imagine something being pulled under water by a current, sinking out of sight.
For ボツ, picture a boat sinking and disappearing with a sudden 'botsu' sound as it goes under: botsu -> ボツ.
