Subject-verb agreement:

Subject-verb agreement refers to the agreement between the subject (the doer of the action) and the verb (the action itself) in a sentence. They need to agree in terms of number (singular or plural). For example:

Incorrect: The dog barks loudly.
Correct: The dog barks loudly.
Explanation: Here, the subject "dog" is singular, and the verb "barks" agrees with it in number.

Regular and irregular verbs:
Regular verbs follow a consistent pattern when forming their past tense and past participle forms, while irregular verbs do not adhere to any specific pattern. Here's an example of each:

Regular verb: Walk
Present tense: I walk to school every day.
Past tense: I walked to school yesterday.
Past participle: I have walked to school many times.

Irregular verb: Go
Present tense: I go to the park every weekend.
Past tense: I went to the park yesterday.
Past participle: I have gone to the park many times.

Identifying antecedents:
An antecedent is a noun or pronoun that a pronoun refers back to in the sentence. It is essential to clearly identify the antecedent for proper sentence clarity. Take a look at the example below:

Example: John and Sarah went to the movies. They enjoyed the film.

In this sentence, "John and Sarah" is the antecedent for the pronoun "they".

Pronoun-antecedent agreement:
Pronoun-antecedent agreement deals with ensuring that pronouns match their antecedents in terms of number (singular or plural). Here's an example:

Incorrect: Mary left their bag at home.
Correct: Mary left her bag at home.
Explanation: The pronoun "their" does not agree with the singular antecedent "Mary". We should use "her" to ensure agreement.

Pronoun case:
Pronoun case refers to the correct form of a pronoun to use in a sentence based on its function (subject, object, or possessive). Consider this example:

Subject case: She loves to read books.
Object case: The teacher gave the book to her.
Possessive case: That is his car.

Pronoun case for "who" and "whom":
"Who" is used as the subject of a sentence or clause, while "whom" is used as the object. Here is an example:

Who: Who is going to the party tonight?
Whom: To whom did you give the invitation?

Vague pronouns:
Vague pronouns provide unclear or ambiguous references to their antecedents. Here's an example:

Incorrect: Lisa has a book, and she loves reading it.
Correct: Lisa has a book, and she loves reading books.
Explanation: The pronoun "it" is vague and does not clearly refer to the noun "book." In the corrected sentence, the pronoun "books" provides a more specific reference.
