sheep
羊 centers on the animal sheep, including its use as a component in other characters.
羊 is a pictograph of a sheep, with the modern form showing horns, a face, and a body. The character has retained its sheep meaning throughout history.
The top strokes look like the curved horns of a sheep, the middle horizontal lines its face, and the vertical stroke its body. Together, 羊 is a sheep.
