The short answer
“Help” is an uncountable noun in English — like “information” or “furniture” — so it can never take “one” in front of it. “I need one help” is a direct translation from Hindi, where “ek” (one) is used loosely for “a” or “some.” Say “I need some help” or “I need a favour” instead.

Why Do People Say It?
In Hindi, “ek” (one) doubles as a loose stand-in for “a” or “some” — “ek madad” can mean “a help”, “some help”, or “a favour”, depending on context. English draws a strict line between countable nouns (which can take “one”, “a”, or a plural — like “favour”) and uncountable nouns (which cannot — like “help”, “advice”, or “information”). Speakers carry the Hindi pattern straight into English without adjusting for this distinction.
This is the same uncountable-noun trap behind “informations” and “furnitures” — “help” simply never takes a number or a plural “-s”.
Exam tip
In SSC error-spotting and IELTS Speaking, replace “one help” with “some help”, “a bit of help”, or the countable noun “favour” (“one favour”, “a favour”). This is the same fix used for every other uncountable noun on this site — never attach “one” or a plural to information, advice, furniture, or luggage.
Frequently Asked Questions
Is 'one help' grammatically wrong?+
Yes. 'Help' is an uncountable noun in English, so it cannot be counted with 'one', 'two', or a plural form. Standard English uses 'some help', 'a bit of help', or the countable noun 'favour' instead — 'one favour' is fine, but 'one help' is not.
Why do people say 'I need one help'?+
It is a direct translation from Hindi and other Indian languages, where the word 'ek' (one) is used loosely to mean 'a' or 'some', and where the equivalent word for help does not carry the same strict countable/uncountable distinction that English enforces.
What should I say instead of 'one help' in formal English?+
Say 'I need some help', 'I need a bit of help', or, if you mean a specific single request, 'Can I ask you a favour?' — since 'favour' is a countable noun, unlike 'help'.
