Student or Learner
I would like to know here the difference between someone and some one?
Someone: used when we want to refer to a person but we don't know or don't care who:
From googling the phrase +"some one", it is most commonly used in error - the writer actually meant "someone". It might possibly come up in English but it would be very rare. If you see "some one", it is probably an error.
- Someone ate all the cookies!
- If someone helps me, I can finish quickly.
- I hope I find someone to marry.
Here is a link to another thread which basically agrees with what I have said.
