Spiral review-pronouns and subject verb agreement

A pronoun is a word that takes the place of a noun to avoid repetition, such as 'he', 'she', 'it', 'they'.

A vague pronoun is a pronoun that does not clearly refer to a specific noun, making the sentence unclear.

A subject pronoun is a pronoun that acts as the subject of a sentence, such as 'I', 'you', 'he', 'she', 'it', 'we', 'they'.

An object pronoun is a pronoun that acts as the object of a verb or preposition, such as 'me', 'you', 'him', 'her', 'it', 'us', 'them'.

A linking verb connects the subject of a sentence to a subject complement, often describing a state of being, such as 'is', 'are', 'was', 'were'.

A helping verb, or auxiliary verb, is used with a main verb to form a verb phrase, indicating tense, mood, or voice, such as 'is', 'have', 'will'.

The linking/helping verb is 'is'.

The vague pronoun is 'They'.

Subject-verb agreement means that the subject and verb in a sentence must agree in number (singular or plural).

Example: 'The dog barks.' (singular subject 'dog' agrees with singular verb 'barks').
