We are all stumped as to what you would call a term such as "petsmart", where you can use the "s" on either side of the word. Thankyou.

I don't see that you can use the 's' on either side of the word-- I don't even understand your 'word': is it 'pets mart' or 'pet smart'? Neither phrase makes particular sense, though you can have 'pet marts' for buying a 'smart pet'.
