伸
shēn · HSK 5
to stretch
🤸 伸 = 亻(person) + 申 (extend/state); person extending out
申 means to extend or state, and adds the sound shēn. Add 亻for the person doing the stretching. Same shēn as 申 — the person radical just makes it physical: a body reaching out.
伸 — person radical 亻 + 申 (extend/state)
伸 is a semantic-phonetic compound. The left side 亻 (person) gives the meaning, suggesting a body action, while 申 originally depicted lightning stretching across the sky and supplies the sound. Together they convey the idea of a person stretching or extending.
