Literally: middle form

The story of the word

The middle germ layer of the embryo, the mesoderm, becomes bone and muscle, so Sheldon in 1940 handed the muscular build the middle name. His system scored everyone on all three components from one to seven, giving a profile rather than a box; popular use threw away the numbers. μέσος also gives Mesopotamia, the land in the middle of the rivers.
