The Differences between “a number of” and “the number of”

Understanding the nuances of English grammar can be tricky, especially when it comes to similar phrases like “a number of” and “the number of.” While they might seem interchangeable, these phrases have distinct meanings and uses. In this article, we will explore the key differences and provide examples to help you use them correctly.

Overview

“A number of” is used to indicate an unspecified quantity, generally meaning more than two or several without specifying exact figures. It functions as a quantifier rather than a subject. For example, when you say, “A number of students are waiting outside,” you are indicating that several students are waiting, without giving an exact number. The key grammatical rule to follow is that “a number of” must be used with a plural noun and followed by a plural verb.

“The number of” is used to specify a precise quantity. Unlike “a number of,” which refers to an unspecified amount, “the number of” emphasizes an exact figure or count. For example, you might say, “The number of students in the class is 30.” Here, “the number of” refers to the exact count of students in the class. The key grammatical rule to follow is that “the number of” must be used with a plural noun and followed by a singular verb.

The Differences between “A Number of” and “The Number of”

The phrase “a number of” is followed by a plural verb while the phrase “the number of” is followed by a singular verb.

Examples

  1. A number of students have completed their assignments.
  2. A number of factors are affecting the outcome of the experiment.
  3. A number of issues were raised during the meeting.
  4. The number of votes was higher than expected.
  5. The number of pages in the book is 350.
  6. The number of the participants of our contest has doubled this year.

Common Mistakes and Correct Uses

Incorrect: The number of students are increasing.

Correct: The number of students is increasing.

Explanation: This sentence incorrectly uses “the number of” with a plural verb (“are”). “The number of” should always be followed by a singular verb to agree with its singular nature.

Incorrect: A number of participants has arrived late.

Correct: A number of participants have arrived late.

Explanation: Here, “a number of” is incorrectly paired with a singular verb (“has”). Despite “participants” being plural, “a number of” requires a plural verb to match the plural noun it precedes.

Incorrect: A number of pages is missing from the report.

Correct: A number of pages are missing from the report.

Explanation: This sentence incorrectly uses a singular verb (“is”) with “a number of,” which should take a plural verb to agree with the plural noun (“pages”).

Incorrect: The number of people are happy with the decision.

Correct: The number of people is happy with the decision.

Explanation: Here, “the number of” is followed by a plural verb (“are”), which is incorrect. It should be followed by a singular verb because it refers to a single count or quantity.

Summary

Both “a number of” and “the number of” are used with plural nouns. The main differences are “a number of” refers to an unspecified quantity and is followed by a plural verb while “the number of” refers to a precise quantity (or it would be expected that the speaker knows the number in question) and is followed by a singular verb.

“Is it me” Or “Is it I?”

When it comes to grammar, few debates ignite as much passion and confusion as the choice between “It is me” and “It is I.” Whether you’re a descriptivist or a presciptivist, this question has likely sparked a moment of doubt or even heated discussion. In the ever-evolving world of English, where rules bend and shift with usage, understanding the nuances of this seemingly simple sentence can reveal much about how we communicate today. Dive in as we explore why “it is me” has become the go-to in everyday speech and what makes “it is I?” the grammatically correct choice according to traditional rules.

According to the traditional grammar rules, the pronoun ‘me’ should not be placed after a linking verb.

When a pronoun follows a linking verb, the pronoun should be in the subject position (nominative case). She is my lady = My lady is she (“she is my lady” equals “my lady is she”).

Although “it is me” sounds more natural and is typically used in everyday conversation. ‘It is I’ is grammatically correct because the subject complement (after a linking verb) should be in the nominative case.

Please keep in mind that in written or academic settings, adhering to traditional grammatical rules might be expected, making “it is I?” the appropriate choice. In informal contexts or everyday conversation, the emphasis is often on clarity and natural flow, so using the objective case ‘me’ after a linking verb is now acceptable and sounds more natural to modern speakers.

Subject and Verb Agreement

Subject-verb agreement in English grammar means the verb must match the subject in number and person. If the subject is singular, the verb must be singular. If the subject is plural, the verb must be plural.

However, English has many irregular verbs and exceptions to general rules, making it difficult for learners to apply consistent logic. Subject-verb agreement can be particularly challenging for learners as English sentences can be complex, containing multiple clauses and phrases that can obscure the subject and the verb.

For instance, in the sentence “The teacher, along with her students, is going to the museum,” some learners might be misled by the noun closest to the verb (her students) rather than the actual subject (the teacher).

Here are subject and verb agreement rules that English learners need to know: 

Table of Contents

Rules

Rule 1. All subjects except third-person singular use the base form of a verb in the present tense.

All subjects except third-person singular use the base form of a verb in the simple present tense.

Examples: I read every day.

They read every day.

However, if the subject is third-person singular, add an –s to the end of the verb.

Example: She reads every day.

If a verb ends in -s, -ss, -sh, -ch, -x, or -z, add –es to the verb.

Examples:

Base form: “pass”

Third-person singular: “She passes the final test.”

If a verb ends in a consonant followed by -y, change the -y to -i and add –es to the verb.

Example:

Base form: “cry”

Third-person singular: “He cries loudly.”

If a verb ends in a vowel followed by -y, simply add –s to the verb.

Example:

Base form: “play”

Third-person singular: “She plays piano.”

Base FormThird-Person SingularExample Sentence
walkwalksHe walks to school.
passpassesShe passes the final test.
washwashesHe washes the car.
fixfixesShe fixes the computer.
crycriesHe cries loudly.
trytriesShe tries her best.
playplaysHe plays the piano.
enjoyenjoysShe enjoys reading.
Third-person singular verbs in simple present tense.

Rule 2. A singular subject (one person, thing, or idea) takes a singular verb (ends in -s or -es in the present tense) and a plural subject (more than one person, thing, or idea) takes a plural verb (without -s or -es in the present tense).

singular subject (one person, thing, or idea) takes a singular verb (ends in -s or -es in the present tense). A plural subject (more than one person, thing, or idea) takes a plural verb (without -s or -es in the present tense).

Example:

“The cat walks slowly.”

“Cat” is singular, so the verb “walks” is also singular.

Example:

“The cats walk slowly.”

“Cats” is plural, so the verb “walk” is also plural.

Rule 3. When two subjects are joined by “and,” they take a plural verb.

When two subjects are joined by “and,” they take a plural verb.

Example:

“The cat and the dog sit together.”

“Cat” and “dog” together are plural, so the verb “sit” is plural.

Rule 4. When subjects are joined by “or” or “nor,” the verb should agree with the subject closest to it.

When subjects are joined by “or” or “nor,” the verb should agree with the subject closest to it.

Example:

“Either the cat or the dogs are in the living room.”

“Dogs” is closer to the verb and is plural, so the verb “are” is plural.

Example:

“Neither the dogs nor the cat is in the living room.”

“Cat” is closer to the verb and is singular, so the verb “is” is singular.

Rule 5. Some indefinite pronouns always take singular and take a singular verb although they seem to refer to multiple people or things.

Singular Indefinite Pronouns:

  1. Anybody/ anyone/ anything

Examples:

Does anybody need help with their work?

Has anyone got a pencil?

Anything is possible with hard work.

Despite referring to an unspecified group, “anybody” and “anything” take singular verbs (“does,” “has”, and “is”).

2. Everybody/ everything

Examples:

Everybody enjoys the concert.

Everything is ready for dinner.

Although these pronouns imply all members of a group, they still require singular verbs (“enjoys” and “is”).

3. Somebody/ Someone/ Something

Examples:

Someone needs to talk to the teacher.

Something smells good in the kitchen.

These pronouns refer to an unspecified individual or thing, and use singular verbs (“needs” and “smells”).

4. Nobody/ No one /Nothing

Examples:

Nobody knows the answer.

Nothing is impossible.

Even though these pronouns refer to the absence of people or things, they still take singular verbs (“knows” and “is”).

5. Each

Example:

Each of the students has a new book.

“Each” emphasizes individual members of a group, so it takes a singular verb (“has”).

6. Either/Neither

Examples:

Either option is acceptable.

Neither of the answers was correct.

“Either” and “neither” refer to one out of two choices and require singular verbs (“is” and “was”).

7. One

Example:

One of the tables is missing.

“One” specifies a single item out of a group, needing a singular verb (“is”).

8. Another

Example:

Another mistake has been made.

“Another” refers to an additional item or person, and uses a singular verb (“has”).

Rule 6. Some indefinite pronouns (e.g., few, many, several) are always plural and take a plural verb.

Example: “Many enjoy the concert.”

“Many” is plural, so the verb “enjoy” is plural.

Rule 7. Parentheses are not part of the subject.

Correct:

Incorrect:

Rule 8. If the sentence begins with there or here, the subject follows the verb.

Correct:

Incorrect:
