Has and have are considered to be different conjugations of the same verb. They are just used differently depending on the subject that is being used in the sentence. For example, if the noun that is being used is in its singular form, it is already common that the term that will be used to follow the singular noun is "has."
If in case the noun that is being described in the sentence is in plural form, it is the term "have" that will be used. To provide a sample sentence, you can say, “She has purchased ten apples.” You are going to use “has” in order to connect the pronoun with another action verb.
The word has the third person singular present tense of the verb has. Some examples of sentences include "She can sing," "The cat has the mouse in his mouth.", "She has a pen in her hand," and "He has a big house" These are all examples of sentences with the word," has"The word had, on the other hand, is the past tense of the transitive word, had.
Here are a few examples: "She had dinner at the restaurant," "He had the flu," "They had no option.," and "He had no right to do this.." The one key difference between these two words is tense.
