Croft's comparative concept
numeral (SEM):

numeral (SEM) = a word that specifies the precise cardinality of a set of referents. Numerals most typically are packaged as modifiers. Two common types of numerals are cardinal numerals and ordinal numerals (there are other types not discussed here); see also vague numerals. Example: in three women, three is a cardinal numeral functioning as a modifier of women. (Section 4.1.3)
