uncountable

Too many to be counted or measured. / In grammar, referring to a noun that cannot be counted as individual units and therefore has no plural form. / In mathematics, referring to a set that is too large to be put into a one-to-one correspondence with the set of natural numbers.
Adjective

This term describes a state of vastness or indivisibility. In general usage, it evokes a sense of overwhelming quantity, often used poetically to describe the cosmos or the sands of a beach, where the act of counting becomes a futile exercise.

In technical domains, the word shifts from a description of quantity to a description of nature. In linguistics, it identifies substances or abstract concepts that lack discrete boundaries, while in set theory, it defines a specific cardinality of infinity that exceeds the countable infinity of integers.
