To inflect adjectives into comparative and superlative forms.

§1. Constructing comparatives. In English, the comparative of an adjective can generally be formed by suffixing the inflected form with "than"; thus, "big" to "bigger than". The following does the suffixing: 

    <comparative-construction> ::=
        ... than

§2. 

    wording Grading::make_comparative(wording W, PREFORM_LANGUAGE_TYPE *nl) {
        TEMPORARY_TEXT(comprised);
        TEMPORARY_TEXT(transformed);
        if (*(Lexer::word_text(Wordings::first_wn(W))) == '\"')
            WRITE_TO(comprised, "some-long-text");
        else
            WRITE_TO(comprised, "%N", Wordings::first_wn(W));
        if (nl == NULL) nl = English_language;
        match_avinue *comp_trie =
            Preform::Nonparsing::define_trie(<adjective-to-comparative>, TRIE_END, nl);
        Inflections::suffix_inflection(transformed, comp_trie, comprised);
        wording PW = Feeds::feed_stream(transformed);
        word_assemblage merged =
            Preform::Nonparsing::merge(<comparative-construction>, 0,
                WordAssemblages::from_wording(PW));
        PW = WordAssemblages::to_wording(&merged);
        LOGIF(CONSTRUCTED_PLURALS, "[Comparative of %W is %W]\n", W, PW);
        DISCARD_TEXT(transformed);
        DISCARD_TEXT(comprised);
        return PW;
    }

    wording Grading::make_superlative(wording W, PREFORM_LANGUAGE_TYPE *nl) {
        TEMPORARY_TEXT(comprised);
        TEMPORARY_TEXT(transformed);
        if (*(Lexer::word_text(Wordings::first_wn(W))) == '\"')
            WRITE_TO(comprised, "some-long-text");
        else
            WRITE_TO(comprised, "%N", Wordings::first_wn(W));
        if (nl == NULL) nl = English_language;
        match_avinue *comp_trie =
            Preform::Nonparsing::define_trie(<adjective-to-superlative>, TRIE_END, nl);
        Inflections::suffix_inflection(transformed, comp_trie, comprised);
        wording PW = Feeds::feed_stream(transformed);
        LOGIF(CONSTRUCTED_PLURALS, "[Superlative of %W is %W]\n", W, PW);
        DISCARD_TEXT(transformed);
        DISCARD_TEXT(comprised);
        return PW;
    }

§3. There has to be a better term than "quiddity" for this grammatical construct, but what I mean is the property for which the given adjective makes a comparison: for instance, "tallness" for "tall", or "steeliness" for "steely". 

    wording Grading::make_quiddity(wording W, PREFORM_LANGUAGE_TYPE *nl) {
        TEMPORARY_TEXT(comprised);
        TEMPORARY_TEXT(transformed);
        if (*(Lexer::word_text(Wordings::first_wn(W))) == '\"')
            WRITE_TO(comprised, "some-long-text");
        else
            WRITE_TO(comprised, "%N", Wordings::first_wn(W));
        if (nl == NULL) nl = English_language;
        match_avinue *comp_trie =
            Preform::Nonparsing::define_trie(<adjective-to-quiddity>, TRIE_END, nl);
        Inflections::suffix_inflection(transformed, comp_trie, comprised);
        wording PW = Feeds::feed_stream(transformed);
        LOGIF(CONSTRUCTED_PLURALS, "[Quiddity of %W is %W]\n", W, PW);
        DISCARD_TEXT(transformed);
        DISCARD_TEXT(comprised);
        return PW;
    }
