Learn English – Expressing infinite amounts


I know

There is an infinite number of prime numbers

is correct. But is

There are infinite prime numbers

correct as well?

Best Answer

Your first sentence is correct, but has the stylistic disadvantage of repeating the word "number". Your second sentence is wrong; "infinite" is usually only applied as an adjective to uncountable nouns (e.g., "infinite space"). The standard way to rephrase the first sentence without repeating the word "number" is

There are infinitely many prime numbers.
