ABSTRACT
Both adjectives and adverbs can inflect for degree with comparative and superlative forms. The most usual case for marking comparative and superlative of adjectives is to mark it syntactically, by adding more before the adjective to mark the comparative and most before the adjective to mark the superlative. Usage is determined by a number of factors, including the phonological structure of the adjective, the morphological structure of the adjective, the syntactic structure in which the comparative is used, the lexical environment in which the construction is used, and even what the recent exposure of the speaker has been to the two constructions. There is a set of adverbs with irregular comparative and superlative. Just as there is some vacillation in the use of adjective forms for adverbs, there is some variation in the use of comparative and superlative forms.
