Don't vs. Doesn't
Definition
Don't is the contraction of do not. Doesn't is the contraction of does not. Use doesn't with singular subjects except I and you. Use don't with plural subjects and I and you.
Explanation
Use doesn't with singular subjects except for I and you. This includes words like he, she, it, or a single noun like the team. For plural subjects like they or the students, and for I and you, you should always use don't. It's all about making the verb agree with its subject!
Examples
- My brother doesn't play video games. [The subject is singular, so the contraction is doesn't.]
- The new students don't know the school rules yet. [The subject is plural, so the contraction is don't.]
- I don't think that's the right answer. [The subject of the verb is I, so the contraction is don't.]
