Speaking of terminology, I'd also love some visual examples of bad mesh formations.

I think I have a good handle on what a Tri is but..

Ngons = polygon with 5+ edges??

Star = a vertex that connects more than 4 edges??

what else do we have to look out for..

 

Sorry for all the noobish questions here...  I've played around a fair bit with modelling now but I feel like I'm due for an understanding check
