Some linguists approach the number of the degrees of comparison as problematic on the grounds that the basic form of the adjective does not express any comparison by itself and therefore should be excluded from the category. This exclusion would reduce the category to two members only, i.e. the comparative and superlative degrees.
However, the oppositional interpretation of grammatical categories underlying our considerations does not admit of such an exclusion; on the contrary, the non-expression of superiority by the basic form is understood in the oppositional presentation of comparison as a pre-requisite for the expression of the category as such. In this expression of the category the basic form is the unmarked member, not distinguished by any comparison suffix or comparison auxiliary, while the superiority forms (i.e. the comparative and superlative) are the marked members, distinguished by the comparison suffixes or comparison auxiliaries.
On the other hand, due to the tendency of colloquial speech to contrastive variation, such extreme qualifiers can sometimes be modified by intensifying elements. Thus, "the final decision" becomes "a very final decision"; "the ultimate rejection" turns into "rather an ultimate rejection"; "the crucial role" is made into "quite a crucial role", etc.
As a result of this kind of modification, the highest grade evaluative force of these words is not strengthened, but, on the contrary, weakened; the outwardly extreme qualifiers become degraded extreme qualifiers, even in this status similar to the regular categorial superlatives degraded in their elative use.
