The principal ways of forming an adjectival phrase are positive, comparative, relational, reflexive-relational, and elliptic-relational. (The superlative use is covered in Noun.`SuperlA`.)

            PositA  : A -> AP ;         -- warm
            ComparA : A -> NP -> AP ;   -- warmer than Spain
            ComplA2 : A2 -> NP -> AP ;  -- divisible by 2
            ReflA2  : A2 -> AP ;        -- divisible by itself
            UseA2   : A2 -> A ;         -- divisible

Sentence and question complements defined for all adjectival phrases, although the semantics is only clear for some adjective.

            SentAP  : AP -> SC -> AP ;  -- great that she won, uncertain if she did

An adjectival phrase can be modified by an adadjective, such as very.

            AdAP    : AdA -> AP -> AP ; -- very uncertain

The formation of adverbs from adjective (e.g. quickly) is covered by Adverb.
