What Is the Difference Between “Do” and “Does”?

[BrunoWalli]

I often get confused about when to use do and does in sentences. Can someone explain the difference between do vs does with simple examples?

“Do” and “Does” are both auxiliary verbs used to form questions or negatives. “Do” is used with plural subjects and “I,” “you,” “we,” “they,” while “does” is used with singular third-person subjects like “he,” “she,” or “it.” Example: “Do you like coffee?” versus “Does she like coffee?”

“Do” and “Does” are forms of the verb to do.

• Use “do” with I, you, we, and they.
• Use “does” with he, she, and it.

Examples:

• I do my homework.
• She does her homework.
