Understanding the Basics
* "Has" and "have" are the present tense forms of the verb "to have." They indicate possession, existence, or actions in the present.
* "Had" is the past tense form of "to have." It indicates possession, existence, or actions that occurred in the past.
Choosing the Right Form
1. Subject-Verb Agreement: The key is to match the form of "have" to the subject of your sentence.
* Singular Subjects: Use "has" with singular subjects (e.g., she, he, it, the dog).
* *She has a new car.*
* *The dog has a bone.*
* Plural Subjects: Use "have" with plural subjects (e.g., they, we, you, the dogs).
* *They have many friends.*
* *We have a lot of homework.*
2. Past Tense: Use "had" to express actions or states of being in the past.
* *She had a great time at the party.*
* *The dog had a bone yesterday.*

Common Mistakes
