Final answer:
In English, the person or people who are being spoken to are referred to as the second person and 'you' is used as the pronoun.
Step-by-step explanation:
In English, the person or people who are being spoken to are referred to as the second person. When talking to one person, 'you' is used as the pronoun (singular). When speaking to more than one person, 'you' is still used, but it is considered the plural form of the pronoun.
