Lexical gaps
As I was reading Ch. 10 and Cruse was discussing body parts I was thinking about the lexical gaps we have when talking about our toes. For our fingers we have: index, middle, ring, and pinky finger, but for the toes we only have: big toe and pinky toe. At least as far as I know there are no names, specifically, for the other three in between. Any thoughts or answers?

I would venture to guess that we don't have names for the other three toes because:
we don't point with our 'index' toe, nor do we traditionally wear rings on our 'ring' toe, and best of all we can't give anyone the 'middle' toe.
I think funtion/importance is the best explanation for why the toes aren't getting as much lexical attention.
