Etymology

Origin of mesomorph

First recorded in 1935–40; meso- + -morph

Explanation

If you're a big, strong, muscular person, you can describe yourself as a mesomorph. There is a theory of body types and the way they relate to personality called "constitutional psychology." An important part of this idea divides people into three categories based on their bodies — a mesomorph is the strongest type, with prominent muscles and very little body fat. The theory, developed in the 1940's, is now considered outdated. Mesomorph combines the Greek words mesos, "middle," with morphe, "form."
