Staffage

Staffage is the visual arts equivalent of minor characters in a novel. They're animals or people in the background. Part of the scene, but not the subject.

As I can't draw, I'm attempting to illustrate this through photos of a crow. In one he's the central character, the subject - in the other he's really just staffage. See what I mean?

Hobbledehoy

A hobbledehoy is a clumsy or awkward youth. I was one of them a loooong time ago, though I don't recall being referred to as such.

Is there a term for a similar adult? If so, that'll be me now.
