Number and Person

The Duality of Count and Perspective: Mastering How Words Reflect Quantity and Relationship

---

What Is Number?

A Simple Story to Begin

Imagine you’re looking at the night sky. If you see one star, you say, “Look at the star.” If you see dozens, you say, “Look at the stars.” The form of the word changes to tell your listener whether you’re talking about one or many. That change is called number.

In grammar, number tells us whether a word refers to one (singular) or more than one (plural). It affects nouns, pronouns, and verbs—and getting it right is essential for clear communication.

Definition of Number

Number is a grammatical category that indicates the quantity of a noun, pronoun, or verb. There are two numbers in English:

---

Number in Nouns

Most nouns in English change form to show plural. The most common way is to add -s or -es.

Regular Plural Nouns

Irregular Plural Nouns

---

Number in Pronouns

Pronouns change form depending on whether they are singular or plural. This is especially important because pronouns must agree with the nouns they replace.

Note: You is unique—it can be singular or plural, but the form doesn’t change. We understand the number from context.

---

Number in Verbs

Verbs change form to agree with the number of the subject. This is most noticeable in the present tense and with the verb be.

Special Cases and Considerations

1. Uncountable Nouns: water, rice, information. Treated as singular.
2. Collective Nouns: team, family. Can be singular or plural based on unit vs individuals.
3. Always Plural Nouns: scissors, trousers, glasses.
4. Titles and Names: “The Chronicles of Narnia” is a classic.
5. Amounts and Quantities: Fifty dollars is too much (one sum).

What Is Person?

A Simple Story to Begin

Imagine you’re at a gathering with two friends. You say, “I am hungry.” You’re talking about yourself—the speaker. Your friend replies, “You should eat something.” Now they’re talking directly to you—the listener. Then the other friend says, “She is always hungry.” Now they’re talking about someone else—the one being spoken about.

These three roles—the speaker, the listener, and the one being spoken about—are the three persons in grammar.

---

Definition of Person

Person is a grammatical category that indicates the role of a noun or pronoun in relation to the speaker.

---

First Person – The Speaker

First person refers to the person or people speaking. It can be singular (I) or plural (we).

---

Second Person – The Listener

Second person refers to the person or people being addressed. In English, you is used for both singular and plural.

A Simple Story to Begin
Imagine you’re directing a small play. You have three actors: the Speaker (first person), the Listener (second person), and the One Being Spoken About (third person). But each of these roles can be played by either one person (singular) or a group (plural). A single speaker says, “I am ready.” A group of speakers says, “We are ready.” The verb changes to match both who is speaking and how many are speaking.

In grammar, number and person are inseparable partners. They work together to determine the correct form of pronouns and verbs. Understanding this partnership is the key to mastering agreement.

---

How Number and Person Combine

Every noun or pronoun in English has a person (1st, 2nd, or 3rd) and a number (singular or plural). Together, they create six grammatical categories:

Notice:

• Second person uses the same pronoun forms for singular and plural (you), but the reflexive form differs (yourself vs. yourselves).
• Third person singular has the most variety: he, she, it, and all singular nouns.
• Verbs change based on both person and number, especially in the present tense.

---

The Verb Be – A Complete Picture

The verb be is the most irregular verb in English. It shows the full combination of person and number in both present and past tenses.

---

Present Tense of Regular Verbs

For most verbs, the only distinction in present tense is the third-person singular -s ending. All other persons (1st singular, 2nd singular, 1st plural, 2nd plural, 3rd plural) use the base form.

Examples:

• I run every morning. (1st singular)
• She runs every morning. (3rd singular)
• They run every morning. (3rd plural)

Key Rule: The -s ending marks third person singular in present tense. No other person-number combination takes that ending.

Pronoun Agreement in Number and Person

A Simple Story to Begin
Imagine you’re telling a friend about your neighbor, Maria. You say, “Maria is an artist. She paints beautiful landscapes.” You used she to replace Maria. If you had said, “They paint beautiful landscapes,” your friend would be confused—they doesn’t match Maria in number (singular) or person (third person feminine). The pronoun and its antecedent must agree.

Now imagine you’re talking about yourself and your brother: “My brother and I built a treehouse. We finished it yesterday.” Here we matches the plural first-person antecedent. When pronouns and their antecedents don’t agree, meaning gets tangled. Agreement ensures clarity.

Definition: Pronoun-Antecedent Agreement

A pronoun is a word that takes the place of a noun (e.g., he, she, it, they, we, you). The noun that the pronoun refers to is called the antecedent (from Latin ante = before, cedere = to go—the noun that goes before).

The rule of pronoun-antecedent agreement is simple: a pronoun must agree with its antecedent in number (singular or plural) and person (first, second, or third).

Examples:

• The dog wagged its tail. (dog = 3rd singular → its)
• The dogs wagged their tails. (dogs = 3rd plural → their)
• I finished my homework. (I = 1st singular → my)
• You should bring your own lunch. (you = 2nd → your)

---

Agreement in Number

The pronoun must match the antecedent’s number: singular antecedent → singular pronoun; plural antecedent → plural pronoun.

Singular Antecedents

Plural Antecedents

---

Agreement in Person

The pronoun must match the antecedent’s person: first person (I/we), second person (you), or third person (he/she/it/they).

Examples of Person Agreement

Common Person‑Shift Errors
Shifting person without reason confuses readers.

• Wrong: If a person exercises regularly, you will feel healthier. (shifts from 3rd to 2nd)
• Right: If a person exercises regularly, they will feel healthier. (consistent 3rd)
• Right: If you exercise regularly, you will feel healthier. (consistent 2nd)

---

Special Cases and Challenging Antecedents

1. Indefinite Pronouns (Always Singular)

Indefinite pronouns like everyone, everybody, someone, somebody, no one, nobody, anyone, anybody, each, either, neither, one are third person singular. Traditional grammar required singular pronouns (he or she). Today, singular they is widely accepted as a gender‑neutral alternative.

Note: In formal writing, you may still see "his or her", but "they" is now standard in most contexts.

2. Collective Nouns

A collective noun (e.g., team, family, jury, committee) can take a singular or plural pronoun depending on meaning.

• Singular (acting as a unit): The team celebrated its victory.
• Plural (acting as individuals): The team put on their uniforms and went to their positions.

3. Compound Antecedents

• Joined by "and" → usually plural.

  • Rohan and Sohan finished their homework.
  • Exception: if the two parts form a single unit, singular (e.g., Bread and butter is delicious with its creamy texture.).

• Joined by "or" or "nor" → pronoun agrees with the nearer antecedent.

  • Neither Rohan nor his friends completed their assignments. (friends = plural → their)
  • Neither his friends nor Rohan completed his assignment. (Rohan = singular → his)

4. Singular They for Unknown Gender

When the antecedent’s gender is unknown or non‑binary, they is the standard choice.

• A student left their backpack in the library.
• The caller said they would call back.

5. Titles and Company Names

Even if a title or company name ends with a plural word, it is treated as singular and takes a singular pronoun.

• “The Chronicles of Narnia” is a classic; it has sold millions of copies.
• Microsoft announced its new product.

Common Mistakes

Practice – Correct the Pronoun Agreement

For each sentence, identify the antecedent and choose or correct the pronoun to agree in number and person.

1. Every student must submit their assignment by Friday. (Acceptable; strict formal: his or her)
2. The committee reached its decision unanimously. (its for unit action)
3. If anyone calls, tell them I’ll be back soon. (Correct; singular them)
4. Neither the teacher nor the students finished their work. (their matches students)
5. The United States announced its new policy. (Country = singular)
6. Someone left their umbrella in the lobby. (Acceptable; singular they)
7. Maria and I will bring our own snacks. (1st plural)

---

Why Pronoun Agreement Matters

Proper pronoun agreement ensures:

• Clarity – Readers know exactly who or what you’re referring to.
• Consistency – Avoids confusing shifts in person or number.
• Professionalism – Errors in agreement can make writing seem careless.
• Inclusivity – Using singular they respects gender diversity.

---

Summary – Subtopic 4

• Pronoun-antecedent agreement requires a pronoun to match its antecedent in number (singular/plural) and person (1st, 2nd, 3rd).
• Number agreement: singular antecedent → singular pronoun; plural → plural pronoun.
• Person agreement: maintain consistent person; avoid shifting from 3rd to 2nd unnecessarily.
• Indefinite pronouns are singular; use his or her (formal) or they (modern).
• Collective nouns can be singular or plural based on unit vs. individual action.
• Compound antecedents with "and" are plural; with "or/nor" agree with the nearer part.

Subject-Verb Agreement with Number and Person

A Simple Story to Begin
Imagine you’re conducting an orchestra. The subject is the lead violinist. The verb is the note they play. If the violinist plays a solo (singular), the orchestra plays one note. If the violinist is joined by a whole section (plural), the orchestra plays a chord. The music only sounds right when they match.

In grammar, the subject and verb must agree in number (singular/plural) and person (1st, 2nd, 3rd). When they do, the sentence flows smoothly. When they don’t, the reader stumbles. This agreement is the heartbeat of every English sentence.

The Core Principle

A verb must agree with its subject in number and person.

• Number: Singular subject → singular verb; plural subject → plural verb.
• Person: The verb form changes based on the person of the subject (especially in present tense).

Examples:

• I am happy. (1st singular)
• She is happy. (3rd singular)
• They are happy. (3rd plural)

---

Agreement in Number: A Quick Refresher

Exceptions:

1. The verb be is irregular:

   • Singular: I am, you are, he/she/it is
   • Plural: we are, you are, they are

2. Modal verbs (can, could, will, would, shall, should, may, might, must) do not change for number or person.

   • She can swim. / They can swim.

---

Agreement in Person: The Present Tense

The only person that affects verb form in the present tense (aside from be) is third-person singular. All other persons use the base form.

Key Takeaway: If the subject is third-person singular, the verb takes an -s (or -es) ending. For all other subject combinations, the verb remains in its base form.

---

Special Cases That Test Agreement

1. Indefinite Pronouns as Subjects

Most indefinite pronouns are third-person singular and take singular verbs.

• Plural Indefinite Pronouns: few, both, many, several are plural.
  • Few were present.
• Variable Pronouns: some, all, most, none, any – verb depends on the noun after of.
  • Some of the water is gone. (water is singular)
  • Some of the cookies are gone. (cookies is plural)

2. Collective Nouns

Collective nouns (team, family, jury, committee, audience, government) can be singular or plural based on meaning.

• Singular (acting as a unit): The team is celebrating.
• Plural (acting as individuals): The team are arguing.
  (Note: Singular is more common in American English, while plural is widely accepted in British English for collectives.)

3. Subjects Joined by "And"

Usually plural.

• Rohan and Sohan are friends.
• Exception: When the two parts form a single unit or idea, use singular.
  • Bread and butter is my breakfast.
  • The rise and fall of the tide is steady.

4. Subjects Joined by Or / Nor / Either…Or / Neither…Nor

The verb agrees with the closer subject.

• Neither the teacher nor the students are here. (students = plural)
• Neither the students nor the teacher is here. (teacher = singular)

5. "There" and "Here" Sentences

The verb agrees with the subject that follows.

• There is a problem. (problem = singular)
• There are several problems. (problems = plural)

6. Amounts, Periods, Distances, Titles

Treated as singular units.

• Fifty dollars is too much.
• Three years is a long time.
• “The Chronicles of Narnia” is a classic.

7. Relative Clauses (who, which, that)

The verb inside the relative clause agrees with the antecedent.

• She is one of the students who have passed. (antecedent = students → plural)
• She is the only one of the students who has passed. (antecedent = one → singular)

8. Gerunds and Infinitives as Subjects

Always singular.

• Running is good exercise.
• To forgive is divine.

9. "A Number of" vs. "The Number of"

• A number of = many → plural verb.
  • A number of issues remain.
• The number of = a specific count → singular verb.
  • The number of issues is growing.

10. "More Than One" and "Many A"

Both take singular verbs.

• More than one student was absent.
• Many a student has made that mistake.

The Verb Be – A Special Case

Because be has distinct forms for each person and number, it requires extra attention.

Common Mistakes

---

Practice – Choose the Correct Verb

For each sentence, select the verb that agrees with the subject in number and person.

1. The list of items (is / are) on the table.
2. Neither the manager nor the assistants (was / were) informed.
3. Everyone in the two classes (has / have) completed the work.
4. A number of solutions (was / were) proposed.
5. The committee (has / have) not yet reached a consensus.
6. Mathematics (is / are) my favorite subject.
7. There (is / are) several reasons for the delay.
8. She is one of those writers who (never repeats / never repeat) themselves.

Answers:

1. is (list is singular)
2. were (assistants is plural, closer to verb)
3. has (everyone is singular)
4. were (a number of = many)
5. has (committee as a unit)
6. is (mathematics is singular)
7. are (reasons is plural)
8. never repeat (antecedent writers is plural)

Why Subject-Verb Agreement Matters

Mastering agreement helps you:

• Avoid noticeable errors – Agreement mistakes are among the most distracting grammar errors.
• Write clearly – Readers can follow your meaning without interruption.
• Sound professional – Correct agreement signals attention to detail.

---

Summary – Subtopic 5

• Subject-verb agreement requires the verb to match the subject in number and person.
• In the present tense, the only distinct form is third-person singular (verb + -s or -es), except for be.
• Special cases include indefinite pronouns, collective nouns, compound subjects, there sentences, and relative clauses.
• Common mistakes involve mistaking plural-sounding singulars (everyone, mathematics) or mismatched compound subjects.

Common Pitfalls and Exceptions

1. The "You" Ambiguity

Since "you" is the same for singular and plural, we often use words like "you all" (Southern US) or "you guys" (informal) to clarify the number, but in formal writing, "you" remains standard for both.

2. Singular "They"

"They/Them/Their" is now officially sanctioned by major style guides (like APA and MLA) for a person of unknown gender or for non-binary individuals.

• Someone left their jacket here.

3. Relative Pronouns (Who, Which, That)

The verb following a relative pronoun must agree with the noun the pronoun refers to.

• It is I who am responsible. (Agree with I)
• Those are the books that are lost. (Agree with books)
