Meaning of 嫑 and its middle radical
The old character shows hands pulling a head from a woman, which I presume means helping her to have a baby rather than pulling her head off! The middle part is the head and the hands. The fact that the hands only have 3 fingers is proof positive that aliens kidnapped Chinese babies a long time ago. Everyone knows only aliens have 3 fingers!
