island
島 centers on a piece of land surrounded by water: an island.
島 combines 山 (mountain) with a bird-like element that likely represents a phonetic component. The character depicts a mountain rising from the sea, forming an island.
A mountain 山 rises from the sea, with birds flying above it. Together they form an island.
For トウ, imagine a tall island mountain that looks like a toe sticking out of the water: toe -> トウ.
