corpse
屍 centers on a dead body: a corpse. The meaning is concrete and specific, referring to the physical remains of a person or animal.
屍 combines 尸 (a body or corpse) with 死 (death), reinforcing the idea of a dead body. The character is a straightforward semantic compound.
The outer enclosure 尸 represents a body, and inside is 死 (death). Together they show a body that has died: a corpse.
For シ, imagine a scene of a corpse (屍) and think of the word 'she' – but she is dead. 'She' cues シ.
