Components

radical

子 zǐ

child; infant

Child radical on the left — pictograph of a swaddled infant. 孔 originally pictured a baby suckling at the breast, with the curved stroke on the right depicting the breast itself. From 'breast' developed the senses 'opening, hole, passageway' — what the baby drinks through. Same radical heads 字 character, 孩 child, 学 study.

ideograph

乚 yǐ

concealing curve (here a depictive stroke)

Right side is a single curving stroke — historically depicted the mother's breast above the suckling child. In the modern character it functions as a position-marker showing where the opening / aperture is. Pure visual indicator, not phonetic and not a semantic radical with its own family.
