How to use 'countless' in English

'Countless' usually appears directly before a plural noun. Some combinations with prepositions are natural in context, while others are nonstandard.

Quick answer

Common uses of 'countless'

'Countless' normally modifies a plural noun directly: 'countless people' or 'countless times'. 'Countless of' is nonstandard in modern English. Prepositions such as 'in', 'near', and 'from' may appear later in the sentence as separate place or source phrases, not as fixed patterns after 'countless'.

countless times I have warned you.
She helped countless people during the crisis.
They discovered countless species in the region.
