Cat.gf

--1 Cat: the Category System

-- The category system is central to the library in the sense
-- that the other modules ($Adjective$, $Adverb$, $Noun$, $Verb$ etc)
-- communicate through it. This means that a e.g. a function using
-- $NP$s in $Verb$ need not know how $NP$s are constructed in $Noun$:
-- it is enough that both $Verb$ and $Noun$ use the same type $NP$,
-- which is given here in $Cat$.
-- 
-- Some categories are inherited from [``Common`` Common.html].
-- The reason they are defined there is that they have the same
-- implementation in all languages in the resource (typically,
-- just a string). These categories are
-- $AdA, AdN, AdV, Adv, Ant, CAdv, IAdv, PConj, Phr$, 
-- $Pol, SC, Tense, Text, Utt, Voc, Interj$.
--
-- Moreover, the list categories $ListAdv, ListAP, ListNP, ListS$
-- are defined on $Conjunction$ and only used locally there.
