CP-FRL

Adverbial Free Relatives

are treated as in the PPCEME,PPCME2, and they project an NP-ADV in cases like:

Like "hvað sem er" or "hvort sem er":

(NP-ADV (CP-FRL-SPE (WNP-1 (WPRO hvort-hvort))
			   (C sem-sem)
			   (IP-SUB (NP-PRD *T*-1)
				   (NP-SBJ *exp*)
				   (BEPI er-vera))))

NP-PRD idoms CP-FRL

	  (IP-MAT-SPE (NP-SBJ (PRO-N Það-það))
		      (BEPI er-vera)
		      (NP-PRD (CP-FRL-SPE (WNP-1 0)
					  (C sem-sem)
					  (IP-SUB-SPE (NP-SBJ *T*-1)
						      (RDPI verður-verða)
						      (RP til-til)))))))

PP Free Relatives

These tend to occur when a preposition does "double duty" in free relatives.
