Take the other person out
If a phrase names you and someone else, read it with just your pronoun. Choose the form that fits, then put the other person back.
In practice
Maya and I sent the invitation. → I sent the invitation.
They invited Maya and me. → They invited me.
Use me after a preposition
The word between is a preposition. In between you and me, the whole pair is its object. The same pattern works after with, for, and to.
In practice
Keep this between you and me.
There are seats for Maya and me.
Choose the form that fits the comparison or reply
Both than me and than I am work in “Maya is taller than ….” In a comparison that could mean two things, include the verb to show what you mean. For everyday replies, “It’s me” and “Me too” are natural.
In practice
Maya trusts Jo more than I do. → The sentence compares Maya’s trust in Jo with mine.
Maya trusts Jo more than she trusts me. → The sentence compares Maya’s trust in Jo with her trust in me.
