Superlative

Definition and stakes

Joseph Devlin,  How to Speak and Write Correctly

“ Don't use the superlative degree of the adjective for the comparative; as "He is the richest of the two" for "He is the richer of the two." Other mistakes often made in this connection are (1) Using the double comparative and superlative; as, "These apples are much more preferable." "The most universal motive to business is gain." (2) Comparing objects which belong to dissimilar classes; as "There is no nicer life than a teacher." (3) Including objects in class to which they do not belong; as, "The fairest of her daughters, Eve." (4) Excluding an object from a class to which it does belong ”

“ REGULAR COMPARISON OF ADJECTIVES
300. The quality denoted by an adjective may exist in either a higher or a lower degree, and this is expressed by a form of inflection called comparison. The mere presence of the quality is expressed by the positive degree, its presence in a higher or lower degree by the comparative, and in the highest or lowest of all by the superlative.

“ Those which do not admit any comparison, and which we call absolute or supreme superlatives, as
those which are not so absolute, and which we call ordinary superlative, as,
and those which convey the idea of excess, and which we call excessive superlatives, as [34]
As is seen from the preceding examples, the supreme supertive is formed by adding to the beginning of the primitive the prefix gui and by appending to said primitive the affíx i. The first syllable of the primitive may be doubled as use permits.
