Which is correct this is me or it is me?
Both are correct. Technically, it should be “It’s I” or “This is I.” (See Janie Fieb’s answer below for the correct grammar.) However, there is a strong drive among educated English speakers to avoid sounding pedantic or officious, so people generally will say “It’s me” or “This is me.”
Is it this person or these person?
In general, I use it as follows: If I’m using people as the plural of person, then I treat it as plural. These people are going to be the death of me. If people is referring to a community, cultural group, etc.
Is it correct to say someone me?
Both can be correct. The rule is basically that you use the same form that you’d use if you were the only person involved. If you were talking about ownership of a car, you’d say “That car belongs to me”, or if you shared ownership of it, “That car belongs to my wife and me.”
Do you say this is her or this is she?
In English, the non-emphatic subject case is she, and all other forms (object case and emphatic form) are her. Therefore, in natural English the correct answer is “This is her.” This is how non-native speakers learn to say the sentence.
Can we say this is me?
“This is I” is correct technically. “This is me” is what the vast, vast majority of people actually say in practice. “This is me” is not technically correct, but it is what most people say in reality.
Is it wrong to say me someone?
Can we say 100 people?
The traditional rule is that persons is used for either an exact or a small number. So we might estimate that a hundred people were there. Or if we know the exact number, we’d say ninety-eight persons were there.
Can you say me and someone?
It is the convention in English that when you list several people including yourself, you put yourself last, so you really should say “Someone and I are interested.” “Someone and I” is the subject of the sentence, so you should use the subjective case “I” rather than the objective “me”.
Do you say this is him or this is he?
Most English teachers will tell you to say “This is he” and not say “This is him.” This is good advice. It is not common to say “This is I” or “This is me.”
Is the response this is she correct?
“This is she” is grammatically correct. The verb “to be” acts as a linking verb, equating subject and object. So this is she and she is this; “she” and “this” are one and the same, interchangeable, and to be truly interchangeable they must both play the same grammatical role—that of the subject.
