Do or does?

“Do you play soccer?”
“Do you and your brother play soccer?”
“Do your friends play soccer?”
“Does your brother play soccer?”
“Does John play soccer?”

It is clear from the above sentences that you use “does” only when you are talking about someone other than the person you are talking to (you), or when you are talking about more than one person (you and your friends, your friends). So, use “do” when the subject is “you” or if it is plural. Use “does” when the subject is singular and not “you” or “I.”

	Singular	Plural	Use
First Person	I	We	Do
Second person	You	You	Do
Third person		They	Do
Third person	He, She, It		Does
