1. Lesson Overview
In this lesson, you will learn how subject–verb agreement works with indefinite pronouns.
Indefinite pronouns refer to people or things in a general or unspecified way. Examples include:
-
everyone
-
someone
-
anyone
-
each
-
several
-
many
-
none
Because these pronouns do not refer to a specific number of individuals, learners often become confused about whether they require singular or plural verbs.
Some indefinite pronouns are always singular, some are always plural, and some depend on the noun they refer to.
By the end of this lesson, you will be able to:
-
recognise how verbs agree with indefinite pronouns
-
identify pronouns that require singular verbs
-
identify pronouns that require plural verbs
-
understand pronouns whose agreement depends on context
-
avoid common learner errors involving indefinite pronoun agreement
2. Concept Introduction
Consider the following sentence:
Everyone understands the instructions.
Although everyone refers to many people, the pronoun is treated as singular, so the verb is understands.
Now compare another example:
Several researchers analyse the data.
Here several clearly refers to multiple individuals, so the verb is plural.
| Indefinite Pronoun | Verb Form |
|---|---|
| everyone | singular |
| someone | singular |
| several | plural |
3. Core Explanation
Indefinite pronouns behave differently in subject–verb agreement depending on their grammatical category.
Singular Indefinite Pronouns
Many indefinite pronouns always take singular verbs, even though they may refer to many people.
Example:
Everyone participates in the experiment.
Plural Indefinite Pronouns
Some pronouns always require plural verbs.
Example:
Several researchers analyse the data carefully.
Pronouns Depending on Context
Certain pronouns can take singular or plural verbs, depending on whether they refer to countable or uncountable nouns.
Example:
Some of the data are inaccurate.
Some of the information is incomplete.
4. Rule Table
Indefinite Pronouns That Take Singular Verbs
| Pronoun | Example |
|---|---|
| everyone | Everyone understands the procedure. |
| someone | Someone has submitted the report. |
| anyone | Anyone can learn the method. |
| each | Each participant receives instructions. |
| nobody | Nobody knows the exact cause. |
| everybody | Everybody agrees with the results. |
Indefinite Pronouns That Take Plural Verbs
| Pronoun | Example |
|---|---|
| several | Several researchers analyse the data. |
| many | Many scientists study climate patterns. |
| few | Few experiments succeed immediately. |
| both | Both methods produce reliable results. |
Pronouns That Depend on Context
| Pronoun | Example |
|---|---|
| some | Some of the samples are contaminated. |
| any | Any of the equipment is available. |
| none | None of the results are convincing. |
| all | All of the data are accurate. |
| most | Most of the research is reliable. |
The verb depends on the noun following “of.”
5. Usage
1. Agreement with singular indefinite pronouns
Example:
Everyone understands the instructions clearly.
2. Agreement with plural indefinite pronouns
Example:
Several researchers analyse the samples carefully.
3. Agreement with context-dependent pronouns
Example:
Some of the experiments are successful.
4. Agreement with uncountable nouns
Example:
Some of the information is incorrect.
5. Agreement with negative pronouns
Example:
Nobody knows the final outcome of the experiment.
6. Signal Words
Indefinite pronouns often appear with general references to people or quantities.
| Pronoun | Example |
|---|---|
| everyone | Everyone agrees with the conclusion. |
| someone | Someone has completed the analysis. |
| several | Several studies confirm the theory. |
| many | Many researchers investigate this topic. |
| some | Some of the results are surprising. |
Recognising these pronouns helps determine the correct verb agreement.
7. Special Cases
Each and Every
When each or every appears before a compound subject, the verb is singular.
Example:
Each researcher and technician follows the procedure carefully.
None
Traditionally, none is treated as singular, but modern usage often allows plural verbs when referring to countable items.
Example:
None of the experiments are successful.
Both forms may appear, but plural agreement is common in modern usage.
8. Additional Notes
Indefinite pronouns sometimes create confusion because they refer to groups or quantities without specifying number.
Example:
Incorrect:
Everyone know the answer.
Correct:
Everyone knows the answer.
Always remember that many indefinite pronouns function grammatically as singular subjects.
9. Common Errors
⚠ Using plural verb with singular pronoun
Incorrect:
Everyone know the results.
Correct:
Everyone knows the results.
Explanation:
Everyone takes a singular verb.
⚠ Using singular verb with plural pronoun
Incorrect:
Several researcher analyses the data.
Correct:
Several researchers analyse the data.
Explanation:
Several requires a plural verb.
⚠ Confusing context-dependent pronouns
Incorrect:
Some of the information are incorrect.
Correct:
Some of the information is incorrect.
Explanation:
Information is uncountable, so the verb is singular.
⚠ Incorrect agreement with “each”
Incorrect:
Each participant receive instructions.
Correct:
Each participant receives instructions.
Explanation:
Each takes a singular verb.
⚠ Incorrect agreement with “none”
Incorrect:
None of the results is convincing.
(if referring to several results)
Better:
None of the results are convincing.
Explanation:
Plural agreement is common when referring to multiple items.
