[Grading::] Grading Adjectives.
To inflect adjectives into comparative and superlative forms.
@ 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
@ This is essentially a wrapper function for the trie <adjective-to-comparative>.
=
wording Grading::make_comparative(wording W, NATURAL_LANGUAGE_WORDS_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));
nl = DefaultLanguage::get(nl);
match_avinue *comp_trie =
PreformUtilities::define_trie(<adjective-to-comparative>, TRIE_END,
DefaultLanguage::get(nl));
Inflect::suffix(transformed, comp_trie, comprised);
wording PW = Feeds::feed_text(transformed);
word_assemblage merged =
PreformUtilities::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;
}
@ This is essentially a wrapper function for the trie <adjective-to-superlative>.

@ This is essentially a wrapper function for the trie <adjective-to-quiddity>.
There has to be a better term than "quiddity" for this grammatical concept
(it is some sort of morphological nominalisation) but what I mean is the
property of which the given adjective makes a comparison: for instance,
"tallness" for "tall", or "steeliness" for "steely".
