The two main ways of forming adverbs are from adjectives and by prepositions from noun phrases.

            PositAdvAdj : A -> Adv ;                 -- quickly
            PrepNP      : Prep -> NP -> Adv ;        -- in the house

Comparative adverbs have a noun phrase or a sentence as object of comparison.

            ComparAdvAdj  : CAdv -> A -> NP -> Adv ; -- more quickly than John
            ComparAdvAdjS : CAdv -> A -> S -> Adv ;  -- more quickly than he runs

Adverbs can be modified by 'adadjectives', just like adjectives.

            AdAdv  : AdA -> Adv -> Adv ;             -- very quickly

Subordinate clauses can function as adverbs.

            SubjS : Subj -> S -> Adv ;               -- when he arrives
            AdvSC : SC -> Adv ;                      -- that he arrives ---- REMOVE?

Comparison adverbs also work as numeral adverbs.

            AdnCAdv : CAdv -> AdN ;                  -- more (than five)
