cardinal number

How many there

A cardinal number is a number that expresses quantity or amount, as opposed to order or position.

Cardinal numbers answer "how many?"—one, two, three, forty-seven, a million—while ordinal numbers answer "which one in sequence?"—first, second, third.

In mathematics, cardinal numbers also describe the size of sets, including infinite sets.

There were seven cardinal sins and seven dwarfs.
