What Is the Difference between 'Anyone' and 'Someone'?
'Anyone' and 'someone' are both indefinite pronouns that refer to an unidentified person. But despite their similarities, are they identical?
Anyone vs. Someone
We can use 'someone' and 'anyone' interchangeably. But they do not have quite the same meaning.
'Someone' is more specific. When we use 'someone' in a question, we are subtly implying that we are sure there is a person responding to our question.
But 'anyone' is more general. It means we are asking a question without particularly expecting an answer.
In the first sentence, we do not assume someone will answer us. We're pretty sure there's no one there. But, in the second sentence, we somehow are implying that we suspect somebody might be there.
Here, you actually mean at least one person has touched your food.
This is a general question you ask a group of people, without any implications or hints.
When you want to talk about a specific person, but you still do not wish to ay whom, instead of 'anyone' you should use 'someone', because it is more specific.
Here, you cannot say 'I'm going out with anyone', because as you are going out with a specific person.
