that can be counted

Adj

Capable of being assigned a bijection to the natural numbers. Applied to sets which are not finite, but have a one-to-one mapping to the natural numbers.

Examples

The empty set is not denumerable because it is finite; the rational numbers are, surprisingly, denumerable because every possible fraction can be assigned a natural number and vice versa.

The word was introduced around the beginning of the 20th century, from Latin denumerō (“to count out”) + -able.
