RP
Following the English corpora, following the Brown corpus, we tag a certain set of words as "RP" any time they do not take a complement.
The Icelandic equivalents to the above list of words (see link) include, at least (this list in progress): Á, AF, FRAM, HJÁ, Í, NIÐUR, MEÐ, OF, TIL, UM, UPP, ÚT, VIÐ, YFIR
(MEÐ and VIÐ not following ppcme2, but following the early new high german corpus and penn yiddish corpus).
Note that Á is tagged RP when it does not take a complement, but P elsewhere. Where Á modifies a PP, it is parsed as an RP specifier of PP where possible.
Note that the following are tagged ADV, projecting an ADVP-DIR or ADVP-LOC: AFTUR, EFTIR, INNAN, INNI, FRAMAN, FRAMMI, OFAN, NEÐAN, NIÐRI, UPPI, UTAN, ÚTI,
These are generally clause (IP)-level constituents, unless they appear in the specifier of a PP, as in the following examples:
(PP (RP Upp-upp)
(P-D af-af)
(NP (N-NSDIC héraði-hérað) (D-PNSD því-það))
(PP (RP Fram-fram)
(P-D af-af)
(NP (N-MSDIC dal-dalur) (D-DMSD þessum-þessi)))
