Pronouns must agree in number and gender.
Pronouns and antecedents agree in terms of number, gender, and person. The pronoun must match the antecedent in these characteristics to ensure clarity and grammatical correctness in the sentence. For example, if the antecedent is singular and masculine, the pronoun that refers to it should also be singular and masculine (e.g., "He went to the store").
An indefinite pronoun and its antecedent agree in number when they are both singular or both plural.
All pronouns must agree with their antecedent in person, number, and gender. This is called pronoun-antecedent agreement.
The subject must agree in number with the verb.
When using pronouns it is important the the pronoun agree with its antecedent (the noun it replaces) in number (singular or plural) and gender (male, female, or neuter).
Informal pronouns like "you" and "I" should be avoided in formal writing. Colloquial pronouns such as "he/she/they" should also be replaced with more formal alternatives like "one" or "individuals."
Should or agree
Some examples of indefinite pronouns that do not agree with the verb in number are "everyone" (singular pronoun) and "they" (plural verb). For instance, the sentence "Everyone were present at the meeting" should be corrected to "Everyone was present at the meeting."
There are no pronouns in the sentence, "An attorney should focus on clients."Examples of the sentence using pronouns:"He should focus on clients.""She should focus on clients.""An attorney should focus on them."
The nominative case pronouns should be used as the subject of a sentence or a clause.Examples:Weate lunch together. (we is the subject of the sentence)Mary, she is the manager, asked if I could work late on Friday. (she is the subject of the noun clause 'she is the manager')
"She will never agree to that" is a complete sentence, and does not contain a possessive pronoun. If the sentence said, "Her cousin will never agree to that," then the word 'her' would be a possessive pronoun.
We all agree that they should not.
