Also, most (all?) English pluralia tantums (or, if one must, pluralia tantum) 
have an optional form preceded by the phrase "pair of."

It seems to me that the reason we have no "nym" word for zero-plurals such as 
DEER is that they don't fit the pattern, e.g., synonym are words that mean 
the same thing, eronyms are names that are derived from work, etc. Zero plurals 
are grammatical categories, not semantic ones.
