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): UPP, FRAM, OFAN ...

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)))
