It flows out quickly out of a hole in large amounts.

I don’t understand why the word ‘amounts’ is used in the plural when it refers only to one hole. Could anyone please enlighten me?

Thanks in advance.

‘amounts’ does not refer to the hole, but to the substance indicated here as ‘it’.

Thanks, Beeesneees.

My doubt is that if ‘it’ is a liquid and is thus uncountable, why is the word ‘amounts’ in the plural?

Although the general rules is to use " amount of + uncountable noun" e.g. amount of money, amount of water, this is a special case where it can be presumed that the spurts ebbed and flowed, so an amount came out, then another amount, then another amount and so on.

‘in large amounts’/‘in csmall amounts’/'in copious amounts, etc. can be used of uncountable nouns in this type of scenario and the phrases are very commonplace.

Ok, now it makes sense.

Thanks a lot, Beeesneees!
