In linguistics, a count noun (also countable noun) is a common noun that can be modified by a numeral and that occurs in both singular and plural form, as well as co-occurring with quantificational determiners like every, each, several, etc. A non-count noun (also mass noun or uncountable noun) is a common noun that is best identified by its syntactic properties, and especially in contrast with count nouns. The semantics of mass nouns are highly controversial. In English, mass nouns are characterized by the fact that they cannot be directly modified by a numeral without specifying a unit of measurement, and that they cannot combine with an indefinite article (a or an). Thus, the mass noun "water" is quantified as "20 liters of water" while the count noun "chair" is quantified as "20 chairs." However, mass nouns (like count nouns) can be quantified in relative terms without unit specification (e.g., "much water," "many chairs").
