Myology
Myology is a noun that refers to the muscular anatomy of a person or animal. The Latin prefix M-Y means muscles, while O-L-O-G-Y is a Greek suffix that means ‘subject or study of interest.’ The myology of that cougar suggests he has a build intended for a predator, with an ability to strike fast at any time. All of this means he’s got a lot of strong and fast muscles, so we’d better get out of here quickly.
