AJ connects adjectives to the word and to create a conjoined modifier phrase.
+-------------Ds-------------+ | +-------A------+ | +---AJ--+---AJ--+ +---Ss--+ | | | | | | the black.a and.j-a white.a cat.n sleeps.vIn the above example, the AJ links join the adjectives black and white to the central coordinator and. The and acts as a head-word, connecting as if it were an adjective itself: joining with an A link to the modified noun on the right. Besides the word and, other verbs or even punctuation can act as a conjunction:
+------Pa-----+---AJra---+ +--Sp-+ +AJla+EBx+ | | | | | | | they taste.v bitter.a , not.e sweet.a
The subtypes AJl, AJr, standing for "left" and "right", are used to maintain sequential ordering, which is important for comma-separated lists of adjectives; thus, for example:
+-------------------Ds------------------+ | +----AJl-----+-------A-------+ | +AJl-+AJr-+ +--AJr---+ + | | | | | | | the black.a , white.a and.j-a orange.a cat.nThe AJ*a subtype is used to conjoin ordinary adjectives, the AJ*c to conjoin comparatives, and AJ*s, AJ*d to conjoin superlatives. Thus, for example:
+--------Pam-------+ | +---AJlc--+---AJrc--+ | | | | this brandy is.v smoother.a-c and.j-c fuller.a-cCertain adverbs can take the AJ*c link, as long as they are also connected by EE- to a modifier that builds a comparative phrase, such as "more", "less", "as":
+---------MVb--------+---------Xc--------+ | +---AJlc---+-----AJrc-----+ | | | +-Xd-+ +--EEy-+ | | | | | | | | we will arrive.v sooner.a-c , yet.j-c as.e-y tired.e , as.e-c they
The AJ*s and AJ*d subtypes are used to conjoin superlatives; the former share one determiner, while the latter uses two:
+------------------Ds-----------------+ +--------La-------+ | | +---AJls--+---AJrs--+ | | | | | | he is the biggest.a-s and.j-s baddest.a-s thug.n in town +-------AJld------+-----------Ds----------+ +---La--+ +-AJrd+---La--+ | | | | | | | he is the biggest.a-s and.j-s the baddest.a-s thug.n in townThe AJ*e subtype is similar, but forces the DD link instead of L:
+----------MVa----------+-----AJre-----+ | +---DD--+---AJle--+ +---DD---+ | | | | | | he ran.v-d the longest.a-s and.j-s the farthest.a-s
