Some specific and narrow grammar rules include:
Subject-verb agreement: In the present tense, the verb "to be" must match the
subject in number and person. For example, "I am" and "he is" are correct, but "I
is" and "he am" are incorrect. For regular verbs, the present tense is formed by
adding -s or -es to the base form of the verb for third-person singular subjects. For
example, "he walks" is correct, but "he walk" is incorrect.
Subject-verb agreement is a grammatical rule that states that the verb in a
sentence must agree in number with the subject of the sentence. In other words,
the verb must be singular if the subject is singular, and the verb must be plural if
the subject is plural. For example, in the sentence "The dog barks," the subject is
"dog," which is singular, so the verb "barks" must also be singular. Conversely, in
the sentence "The dogs bark," the subject is "dogs," which is plural, so the verb
"bark" must also be plural. Pay attention to the subject-verb agreement to ensure
that your sentences are grammatically correct and easy to understand.
Pronoun-antecedent agreement: Pronouns must agree with their antecedent in
number, person, and gender. For example, "he" must refer to a male, "she" must
refer to a female, and "it" must refer to a non-person noun.
The pronoun-antecedent agreement is a grammatical rule that states that a
pronoun used in a sentence must agree in number, person, and gender with the
noun (known as the antecedent) it refers to. This means that the pronoun must
be in the same form as the antecedent concerning number (singular or plural),
the person (first, second, or third), and gender (masculine, feminine, or neutral).
For example, in the sentence "The dog is running in the park. He is having a great
time," the pronoun "he" refers to the antecedent "dog," which is singular and
masculine, so the pronoun "he" must also be singular and masculine.
, Another example is "The students have completed their homework, they can now
relax" Here, "they" refers to the antecedent "students,” which is plural, so the
pronoun "they" must also be plural.
It's also worth noting that when the antecedent is not specified, and the pronoun
is being used to refer to a general idea or a hypothetical person, then there are
gender-neutral pronouns like "they" or "them" that can be used.
It is essential to pay attention to the pronoun-antecedent agreement in order to
avoid confusion and ensure that your sentences are grammatically correct.
Sentence structure: A sentence must have a subject and a verb and express a
complete thought. For example, "The dog" is not a complete sentence because it
does not express a complete thought. "The dog barks" is a complete sentence
because it has a subject ("dog") and a verb ("barks") and expresses a complete
thought.
Sentence structure refers to how the words in a sentence are arranged to form a
grammatically correct and meaningful statement. A basic sentence structure
includes a subject, a verb, and a complete thought.
The subject is the person, place, thing, or idea acting or being described in the
sentence. For example, in the sentence "The dog is running," the subject is "dog."
The verb is the action or state of being performed by the subject. In the sentence
"The dog is running," the verb is "is running."
