Dear MaxQ: My dictionary says hogs are pigs that are ready for market.

My trusty Webster's says: hog, noun.
1. A pig, esp. one that is full-grown
2. An animal related to the pig, as the peccary.

Now I have never heard of a peccary myself, so in looking that up, I found:
peccary, noun. Either of two species of tropical American animals resembling and related to pigs.

Doesn't this appear to be going in circles?
