Adjective
The adjectival-nounal words in question are very specific. They are distinguished by a high productivity and, like statives, are idiomatically characteristic of Modern English.
On the analogy of verbids these words might be called "adjectivids", since they are rather nounal forms of adjectives than nouns as such.
The adjectivids fall into two main grammatical subgroups, namely, the subgroup pluralia tantum {the English, the rich, the unemployed, the uninitiated, etc.), and the subgroup singularia tantum (the invisible, the abstract, the tangible, etc.). Semantically, the words of the first subgroup express sets of people (personal multitudes), while the words of the second group express abstract ideas of various types and connotations.
The category of adjectival comparison expresses the quantitative characteristic of the quality of a nounal referent, i.e. it gives a relative evaluation of the quantity of a quality. The purely relative nature of the categorial semantics of comparison is reflected in its name.
The category is constituted by the opposition of the three forms known under the heading of degrees of comparison: the basic form (positive degree), having no features of corn" parison; the comparative degree form, having the feature of restricted .superiority (which limits the comparison to two elements only); the superlative degree form, having the feature of unrestricted superiority.
It should be noted that the meaning of unrestricted superiority is in- built in the superlative degree as such, though in practice this form is used in collocations imposing certain restrictions on the effected comparison; thus, the form in question may be used to signify restricted superiority, namely, in cases where a limited number of referents are compared. Cf.: Johnny was the strongest boy in the company.As is evident from the example, superiority restriction is shown here not by the native meaning of the superlative, but by the particular contextual construction of comparison where the physical strength of one boy is estimated in relation to that of his companions.
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.
That the basic form as the positive degree of comparison does express this categorial idea, being included in one and the same calegorial series with the superiority degrees, is clearly shown by its actual uses in comparative syntactic constructions of equality, as well as comparative syntactic constructions of negated equality. Cf.: The remark was as bitter as could be. The Rockies are not so high as the Caucasus.
These constructions are directly correlative with comparative constructions of inequality built around the comparative and superlative degree forms. Cf.: That was the bitterest remark I have ever heard from the man. The Caucasus is higher than the Rockies.
Thus, both formally and semantically, the oppositional basis of the category of comparison displays a binary nature. In terms of the three degrees of comparison, on the upper level of presentation the superiority degrees as the marked member of the opposition are contrasted against the positive degree as its unmarked member. The superiority degrees, in their turn, form the opposition of the lower level of presentation, where the comparative degree features the functionally weak member, and the superlative degree, respectively, the strong member. The whole of the double oppositional unity, considered from the semantic angle, constitutes a gradual ternary opposition.
The synthetical forms of comparison in -er and -(e)st coexist with the analytical forms of comparison effected by the auxiliaries more and most.
The analytical forms of comparison perform a double function. On the one hand, they are used with the evaluative adjectives that, due to their phonemic structure (two-syllable words with the stress on the first syllable ending in other grapho-phonemic complexes than -er, -y, -le, -ow or words of more than two-syllable composition) cannot normally take the synthetical forms of comparison. In this respect, the analytical comparison forms are in categorial complementary distribution with the synthetical comparison forms. On the other hand, the analytical forms of comparison, as different from the synthetical forms, are used to express emphasis, thus complementing the synthetical forms in the sphere of this important stylistic connotation. Cf.: The audience became more and more noisy, and soon the speaker's words were drowned in the general hum of voices.
The structure of the analytical degrees of comparison is meaningfully overt; these forms are devoid of the feature of "semantic idiomatism" characteristic of some other categorial analytical forms, such as, for instance, the forms of the verbal perfect. For this reason the analytical degrees of comparison invite some linguists to call in question their claim to a categorial status in English grammar.
In particular, scholars point out the following two factors in support of the view that the combinations of more/most with the basic form of the adjective are not the analytical expressions of the morphological category of comparison, but free syntactic constructions: first, the more/most- combinations are semantically analogous to combinations of less/least with the adjective which, in the general opinion, are syntactic combinations of notional words; second, the most-combination, unlike the synthetic superlative, can take the indefinite article, expressing not the superlative, but the elative meaning (i.e. a high, not the highest degree of the respective quality).
The reasons advanced, though claiming to be based on an analysis of actual lingual data, can hardly be called convincing as regards their immediate negative purpose.
