亲
qīn
parent
one's own (flesh and blood); relative; related; marriage; bride; close; intimate; in person; first-hand; in favor of; pro-; to kiss; (Internet slang) dear
standing (立) + one (一) + small (小) = close kin
The image is of someone standing tall (立) over a small one (小), bound into a single unit (一) — the closeness of a parent leaning over a child. That layered sense of nearness and belonging gave rise to meanings like kin, intimate, and to kiss.
