Quantifiers
Head types
Q - quantifier, positive: fáir 'few'
QR - correlative: færri 'fewer'
QS - superlative: fæstir 'fewest'
WQ - hve 'how', hversu 'how', hvort 'whether', ef 'whether'
Q-heads, other than WQ, are case marked: Q-N, Q-A, Q-D, Q-G; QR-N, QR-A, QR-D, QR-G; QS-N, QS-A, QS-D, QS-G.
Treatment of individual quantifiers
ANNAR, tagged as OTHER; AÐRIR tagged as OTHERS (See also Treatment of individual words)
EINHVER and eitthvað, etc, are tagged ONE+Q (when the meaning is "some"), not ONE+WPRO
HVORTVEGGJA and hvorirtveggja, hvorartveggja, etc., are tagged Q+NUM
HVERGI Q+WADV
Quantifiers without a "special treatment", i.e. tagged as Q:
ALLUR 'everyone', BÁÐIR 'both', EKKERT 'nothing', ENGINN 'no one', HVER, HVOR, NEINN 'no one, (not) any', NOKKUR (and NEKKVAR) 'any, anybody' (usually Q; see Treatment of individual words), MARGUR 'many' (but not mikill and lítill)
EKKI is usually tagged NEG, but with the meaning EKKERT it is tagged Q.
Topicalization or stylistic fronting of quantifiers
See in the PPCME/PPCEME Guidelines
When quantifiers move out of another NP, it is parsed like this:
(IP-SUB (QP-3 (Q-N ENGI-ENGINN)) (RDDI varð-verða) (NP-SBJ (QP *ICH*-3) (ADJ-N líkamleg-líkamlegur) (N-N munúð-munúð)) (PP (P í-í) (NP (N-D holdi-hold) (NP-POS (PRO-G hennar-hún))))
