Treatment of individual words
aðeins, tag as FP=focus particle, cf. only in English
ANNAR, tag as OTHER; AÐRIR as OTHERS
EINN, tag as ONE
FRAM is tagged RP, like English "fro" in the English corpora. Note that as with many of the words tagged RP, when FRAM immediately precedes a preposition heading a PP, it is parsed as a specifier of PP.
GETA when it takes a participle and means "be able to", it is tagged as a modal (MD). See modals MD.
MILLUM, MILLI tagged as N, usually heading the complement NP of the preposition "á" or "í". For cases where MILLI,MILLUM has this same meaning but there is no overt preposition present, it is still tagged N; for the parse in that case, see the guidelines for NP-ADT.
MÓTI tagged "N", even when it means "facing", e.g. "hvor á móti öðrum". In this construction, "móti" is considered a dative N taking an NP-COM, analogously to English "side"; see the PPCME2,PPCEME guidelines on Complements of N and NP-COM.
NÆRRI, see the discussion in ADVP#Complements_of_ADVP and ADJP#Complements_of_ADJ
SEM is usually a complementizer for relative clauses, tagged C. However, when it means 'as', cf. feitur sem svín, 'as fat as a pig', (PP (P sem) (NP svín)), or "It was beautiful, as in the old days", SEM is tagged P. Note that it can take a nominative NP complement in cases such as feitur sem svín. This is consistent with the treatment of "as" in the PPCME2, PPCEME
ÞEGAR, 'when', introduces an adverbial clause, CP-ADV, so þegar Norðmenn tóku ..., 'when Norwegians took ...', is (PP (P þegar) (CP-ADV (C 0) (IP-SUB (NP-SUB Norðamenn) (VBD tóku) (...)))
ÞÓ, ÞÓTT 'while' and ÞÓ AÐ, ÞÓTT AÐ, 'while that', introduce an adverbial clause (cf. PPCME)
Modals taking bare infinitives: MDD, MDP, etc. if finite, if not ...
