NUM: numeral

Definition

A numeral is a word, functioning most typically as a determiner, adjective or pronoun, that expresses a number and a relation to the number, such as quantity, sequence, frequency or fraction.

Cardinal numerals are covered by NUM whether they are used as determiners or not (as in Windows Seven) and whether they are expressed as words (four), or digits (4).

There are numerals belonging to other parts of speech in the universal tagging scheme, based mainly on syntactic criteria: e.g. ordinal numerals are tagged as adjectives or pronouns (first, second, third, …). In Italian there are no adverbial numerals like [cs] poprvé “for the first time” nor multiplicative numerals such as [en] (once, twice).

Note that, since Roman numerals (IV) are only used as ordinal numerals in Italian (Enciclopedia Treccani), are tagged ADJ for coherence with other ordinal numerals. In this case we specify NumType=Ord as morphological feature. A similar treatment is reserved to a cardinal with a suffix such as a, o, esimo, esima, or the symbol ° (similar to the English use of the suffix “th”).

Other words functioning as determiners (including quantifiers such as many and few) are tagged DET.
