1. Find the grammatical head of the subject
Subject–verb agreement concerns the form of a finite verb in relation to its subject. In the present simple, a third-person singular subject normally takes an -s form: “The learner checks the answer.” A plural subject takes the base form: “The learners check the answer.” The verbs be and have have additional irregular forms, so you also need pairs such as is/are and has/have.
The noun nearest the verb is not always the noun that controls it. In “The quality of these recordings is improving”, quality is the head of the subject phrase. Recordings belongs to a prepositional phrase that describes the quality. Cover that phrase temporarily and read “The quality is improving”. This test helps when a long subject separates its head from the verb.
Do not turn the test into a rule that every first noun is the subject. Questions invert word order, relative clauses introduce their own subjects, and introductory phrases can appear before the main clause. Identify the clause you are checking, then ask who or what performs the action or has the stated property. The goal is to connect each finite verb to the correct subject, not to count all the nouns in a sentence.
2. Separate straightforward agreement from variable usage
| Subject pattern | Example | Reason |
|---|---|---|
| Singular head plus plural description | The box of pencils is open. | Box controls is |
| Two separate subjects joined by and | Mina and Ravi are ready. | Two people form a plural subject |
| Each or every plus singular noun | Each participant has a copy. | Each treats members individually |
| Uncountable noun | The equipment is new. | Equipment is uncountable in this use |
| Number expression | A number of learners are absent. | A number of means several |
| The number as a quantity | The number of learners is rising. | The subject is the number itself |
Some agreement choices depend on meaning or English variety. Collective nouns such as team and government can take different agreement patterns when viewed as a unit or as individual members. This lesson does not label one dialect’s ordinary pattern an error. It also avoids mixed-number either/or questions where proximity and editorial style may complicate the choice.
Words such as everyone, someone and nobody take singular verb agreement: “Everyone is ready.” A later singular they can still refer back naturally: “Everyone is ready, and they have their notes.” The pronoun choice does not retroactively make everyone a plural subject. Keep the grammar of each clause separate and avoid “correcting” an accepted pronoun into an awkward sentence.
3. Edit a paragraph by checking one clause at a time
Locate the head before changing the verb
Draft: “The list of topics are on the wall. Each learner have a copy. The examples in the final section shows how the method works.”
Correction: “The list of topics is on the wall. Each learner has a copy. The examples in the final section show how the method works.”
In the first sentence, list is singular even though topics is plural. In the second, each presents learners individually and requires has. In the third, examples is plural; section is merely part of the modifying phrase. The subordinate clause “how the method works” has its own singular subject, method, so works is already correct.
Notice why changing all verbs to singular would fail. Agreement is local to a clause, and the paragraph contains different subject structures. Underline a subject once and its matching finite verb twice. If you cannot explain a correction by connecting that pair, you may be reacting to a nearby noun rather than analysing the sentence.
4. Try twelve focused decisions
Work through all twelve items before opening the explanations. Write your choice or revision and a short reason in a notebook. A correct guess is worth revisiting: the aim is to recognise the relationship in a new sentence, not remember the order of answers.
- Choose: The list of required books is / are online.
- Choose: The books on the top shelf belongs / belong to Ana.
- Choose: Each participant has / have a badge.
- Choose: Every exercise includes / include an explanation.
- Choose: The equipment is / are stored upstairs.
- Choose: Mina and Ravi is / are preparing a presentation.
- Choose: Everyone in these classes needs / need a notebook.
- Choose: A number of learners has / have requested feedback.
- Choose: The number of learners has / have increased.
- Choose: Neither of these two keys opens / open the cabinet. Use conventional formal edited agreement.
- Choose: The tutor who explains these rules works / work here.
- Repair only the agreement error: “The examples in this chapter shows how the system operates.”
5. Check the reasoning, not just the answer
1. Read the answer and explanation
is. List is the singular head noun. Of required books describes the list; books does not control the main verb. Removing the description leaves the clear sentence “The list is online”.
2. Read the answer and explanation
belong. Books is the plural subject. The location phrase does not change its number. Shelf is singular but is not the subject of belong.
3. Read the answer and explanation
has. Each participant presents one member at a time and takes singular agreement. The fact that the event includes many participants does not change the grammatical structure of this subject.
4. Read the answer and explanation
includes. Every is followed by a singular countable noun here, and that subject takes a singular verb. “All exercises include an explanation” is a correct plural alternative with a changed subject structure.
5. Read the answer and explanation
is. Equipment is uncountable in this ordinary meaning. “The pieces of equipment are stored upstairs” would take are because the head noun would then be plural pieces.
6. Read the answer and explanation
are. The subject names two separate people joined by and. They form a plural subject. This is not an expression for one named dish, activity or single combined concept.
7. Read the answer and explanation
needs. Everyone takes singular agreement. The plural noun classes is inside a modifying phrase and does not control needs. A later reference using they would not change this agreement.
8. Read the answer and explanation
have. A number of learners means several learners, so the expression takes plural agreement. Compare the next item, where the subject is a numerical quantity rather than a group of people.
9. Read the answer and explanation
has. The sentence describes a change in the number itself. The head number is singular in this expression, even though learners identifies what is being counted.
10. Read the answer and explanation
opens. Neither of these two keys is treated as singular in the specified formal pattern. Plural agreement does occur in informal usage, so the instruction deliberately states the convention being practised rather than declaring every alternative universally wrong.
11. Read the answer and explanation
works. The main subject is the singular tutor. The relative clause has its own verb, explains, whose subject who also refers to that tutor. The plural rules is an object, not the controlling subject.
12. Read the answer and explanation
“The examples in this chapter show how the system operates.” Examples controls show. System controls operates in the subordinate clause, so that singular verb should remain unchanged. One sentence can require both plural and singular agreement.
6. Check your own long subjects
Take five sentences from a recent paragraph. Put brackets around phrases beginning with of, in, on or with when they modify the subject. Read the subject and verb without those phrases, then restore them. This is a diagnostic aid, not a suggestion to remove useful detail permanently.
For a second pass, mark every clause with its own finite verb. A sentence with a relative clause may contain two agreement decisions, and correcting only the main verb can leave the other problem hidden. Record repeated errors as a pattern, such as “singular head followed by plural noun”, and create a fresh example. Do not include collective-noun variation as an error unless you have checked its intended meaning and the variety of English being used.
