  1. She got some idea.
  2. She got some ideas.
    Which one is correct?
2

Usually:
She got an idea.
She got some ideas.

‘she got some idea’ is correct in the contexts of “began to understand”. For example:
'At first she didn’t understand it at all but she persevered until she got some idea of how it worked and she developed her understanding from there.

I have come across another sentence:
“This graph will give you some idea of levels of ability”.
So it gives me an idea that ‘idea’ can be employed as a plural noun with ‘some’.
Is there any grammar ruling?

4

some idea = begin to understand.

5

Beeesneees,
Do you mean to say ‘some idea’ is a fixed phrase with the meaning ‘begin to understand’?
So it is a some sort of idiom. Is my inference correct?

6

I don’t see it as idiomatic, just one possible meaning.

Hi Allifathima,

‘Idiomatic use’ usually refers to when a word or phrase can’t really be explained logically but is something that is special or peculiar to a particular language. Using ‘some’ in your sentence is simply an example of how ‘some’ can be used to express the idea of ‘to a certain extent’ rather than ‘to a complete or large extent’. If you ask someone a question like this: Can you give me some idea of how this machine works? you are asking for part of an explanation and not a complete explanation.
