Nouns seldom allow comparisons (Schwarzschild 2008: 319): Expressions
like *dogger, *more dog are hardly used. Why do nouns not allow
comparatives, when adjectives do? A comparison requires a well-defi ned
dimension along which the comparison is made. Since many adjectives
are based on one-dimensional domains, a comparative (and a superlative)
then simply involves a comparison of the values along this dimension:
For example, “Oscar is taller than Victoria” means that Oscar’s
coordinate on the length dimension is greater than that for Victoria.
