CP-THT
CP-THT, complement clause (icel. fallsetning) ...
<synttree> [CP-THT [C [að]][IP-SUB[hann-hafi-eitthvað]] ] </synttree>
For cases where a CP-THT is preceded by a PP with a pronominal object, and the pronominal object is interpreted as the CP-THT (the pronoun is just a placeholder for the that-clause), the expression is parsed with the CP-THT as the complement of the pronoun, as in the example below (following the PPCME2,PPCEME guidelines for "because" when written as two separate words, "be cause".
(PP (P-D fyrir-fyrir) (NP (PRO-PNSD því-það) (CP-THT (C að-að) (IP-SUB (NP-SBJ (OTHER-XNSN annað-annar)) (BEP-IA3SP er-vera) (NP-OB1 (N-NPNIC efni-efni) (NP-POS (N-MSGIC bæklings-bæklingur) (D-DMSG þessa-þessi)))))))
Note that the CP-THT clause *immediately* follows the pronoun in this case.
If the pronoun and CP-THT were separated by some other constituent, then the CP-THT would be treated as an extraposed that clause: The object pronoun's NP is labeled e.g. "=1" with the index corresponding to the CP-THT, e.g. "CP-THT-1", in accordance with the guidelines for extraposed that-clauses in the PPCME2, PPCEME. An example follows:
