... may in turn be divided into subfields: INFFLD : nil; inffld( INFI, INF2 ) means that Danish has a possibility of two auxiliaries, (the finite + one infinite), and implicitly that if INF2 ... exist as such. Instead we have: FINIT = finit( VERB, VERB, TEMPG ) INFINIT = infinit( VERB, VERB, TEMPG ) VERB = Symbol which means that a verb, whether it be finite or infinite, is describe...
