Conversation

I've been reading about different body types and learned about the ectomorph.

Oh really? What's an ectomorph like?

They tend to be lean and have a slightly muscular build, which sounds pretty cool.

That does sound interesting! I think I might be more of a mesomorph myself.

Root Explanation

Ectomorph → It is formed from "ecto-" (from Greek "ektos", meaning outside) and "morph" (from Greek "morphe", meaning form or shape). The word describes a body type characterized by a slim, delicate build, suggesting an external or outside form.

Memory Tip

Think of 'outside' ('ecto-') and 'form' ('morph') to remember that an ectomorph refers to a body type that has a slim, outside appearance.
