2.2.1.2 Postverbal subjects and agreement

Postverbal subjects involve no special annotation, unless they do not agree with the verb. In that case, the postverbal argument is annotated NP-ACC and an empty expletive subject is added:
( (IP-MAT (PP (P N@)
	      (NP (D-F @a)
		  (N província)
		  (PP (P de)
		      (NP (NPR Trás-os-Montes)))))
	  (VB-D nasceu)
	  (NP-SBJ (D-UM-F uma)
		  (N vitela)
		  (PP (P com)
		      (NP (NUM-F duas) (N-P cabeças))))
	  (, ,))
  (TYCHO BRAHE; ID G_001,64.980))

( (IP-MAT (CONJ e)
          (NP-SBJ *exp*)
          (VB-D-3S nasceu)
          (PP (P @em)
              (NP (D-F @a)
                  (N praia)))
          (NP-ACC (D-F-P essas)
                  (N-P macieirinhas))
          (. .))
  (CORDIAL-SIN; ID FLF53,8))
If the verb involved is inergative, the non-agreeing NP will instead be co-indexed with the null expletive:
( (IP-MAT (CONJ e)
	  (NP-SBJ-1 *exp*)
	  (VB-P-3S diz)
	  (NP-1 (D-F-P as) (N-P vizinhas))
	  (. :)
	  (IP-IMP-SPE (QT ")
		      (VB-I-2S Vai)
		      (IP-INF (VB @buscá)
			      (NP-ACC (CL @la))
			      (FP já))))
  (CORDIAL-SIN; ID ALV50,85))

( (IP-MAT (CONJ Mas)
	  (NP-SBJ (PRO eu))
	  (TR-D tinha)
	  (FP até)
	  (NP-ACC (COISO coiso)
		  (CP-THT (C que)
			  (PRO ele)
			  (CP-THT (C que)
				  (IP-SUB (NP-SBJ-1 *exp*)
					  (ADVP (ADV ainda))
					  (VB-D-3S funcionava)
					  (, ,)
					  (PP (P por)
					      (ADVP (ADV ali) (ADV assim)))
					  (, ,)
					  (NP-1 (D-UM-F-P umas)
						(N-P coisas)
						(PP (P @de)
						    (NP (D-F-P @essas))))))))
	  (. .))
