One of the Examples Is: Choosing Verbs
Why do we use is instead of are after one of the examples?
One of the examples refers to a single member of a set of examples. In this pattern, use a plural count noun after one of the. The main statement concerns one member, so its verb is normally singular. This is a grammatical pattern, not a claim about whether selection from a one-item set is mathematically possible.
Key points
- Remember that one is the grammatical subject of the main clause, requiring is, was, or has.
- Keep the group noun plural after of.
- When a relative clause describes the plural set, use a plural verb inside that clause, unless the phrase the only one specifies a single item.

Stage 1 of 5
Understand
What it means, when to use it, and mistakes to avoid.
Examples
One of the printers in the office is out of paper.
Why it works: The subject is one, so the verb is the singular is, even though printers is plural.
3 more examples
-
One of my coworkers has submitted the project files.
Has agrees with one coworker, while coworkers names the group.
-
One of the packages that arrived today belongs to Sarah.
The relative clause describes the packages that arrived, but belongs agrees with one.
-
The only one of the laptops that is working is on the desk.
Because of the phrase the only one, the relative clause verb is singular.

Identify the True Subject Before Choosing the Verb
When you read or write a sentence beginning with one of the, your eyes naturally land on the plural noun standing immediately before the verb. That plural noun belongs to a prepositional phrase, which describes the collection rather than the actor. The real subject is the word one at the start of the clause. Because one represents a single unit, you must select a singular verb to match it.
-
One of the files is missing from the folder.
Why it works: The subject is one, so the verb is is, not are.
-
One of our clients has called about the invoice.
Why it works: Has agrees with one client, while clients shows the larger group.
Your turn
Which word is the grammatical subject in the sentence: One of the managers has approved the budget?
Answer: One
Show the answer
Answer: One
The grammatical subject is One. The phrase of the managers simply clarifies which group that individual belongs to.
Select Singular Present Verbs for Everyday Statements
In present tense statements, singular verbs usually end with the letter s, while plural verbs do not. When working with one of the, choose forms like is, has, or works instead of are, have, or work. Learners often make errors here because their ears hear the plural noun right before the verb gap and tempt them to choose a plural form. Always check back to the word one before you speak or write.
-
One of the copy machines needs new toner.
Why it works: Needs has the third-person singular s ending to agree with one.
-
One of my colleagues lives near the train station.
Why it works: Lives is singular because one person lives there.

Your turn
Choose the correct verb: One of the elevators ___ maintenance today.
Answer: needs
Show the answer
Answer: needs
Use needs with the singular subject one. Elevators is plural, but it sits inside a prepositional phrase.
Keep the Group Noun Plural After the Preposition
The group noun after one of the is plural because you are choosing one member of a group. Use students rather than student in this pattern, then choose a singular main verb to agree with one. Check the plural form itself: irregular plurals such as children do not have an -s ending.
-
One of the participants asked an interesting question.
Why it works: Participants is plural because the audience has multiple people.
-
One of the keys unlocks the storage closet.
Why it works: Keys is plural to represent the complete set on the key ring.
Your turn
Which sentence uses the correct noun form after the preposition?
Answer: One of the windows was left open overnight.
Show the answer
Answer: One of the windows was left open overnight.
The noun after of must be plural (windows) to represent the group, and the verb must be singular (was) to match one.
Distinguish Between One Selected Item and the Entire Group
To understand verb choice clearly, contrast a sentence about one member with a sentence about the whole group. When you discuss all members together, the plural noun serves as the direct subject and demands a plural verb. When you introduce one of the, the focus narrows down to a single element. Changing between these two structures completely alters the verb agreement, so you must decide whether your sentence describes one unit or all units.
-
The reports are ready for the executive meeting.
Why it works: The plural noun reports is the subject, requiring the plural verb are.
-
One of the reports is ready for the executive meeting.
Why it works: One report is ready, so the sentence requires the singular verb is.
Your turn
Which grammatical sentence focuses on a single member of the set of contracts?
Answer: One of the contracts has a serious calculation error.
Show the answer
Answer: One of the contracts has a serious calculation error.
One of the contracts has focuses on a single contract. It does not tell us whether any other contracts also have errors.
Apply Singular Forms in Past and Perfect Tenses
Subject agreement remains active when you speak about past events or completed actions. In the simple past, regular verbs keep the same spelling for singular and plural subjects, but the verb be changes between was and were. In the present perfect, you must choose between has and have. With one of the, always pick was and has because the subject remains the singular pronoun one.
-
One of the delivery drivers was delayed by heavy traffic.
Why it works: Was delayed agrees with one driver in the past tense.
-
One of the servers has crashed twice this week.
Why it works: Has crashed agrees with one server in the present perfect tense.
Your turn
Complete the sentence correctly: One of the packages ___ delivered to the wrong address yesterday.
Answer: was
Show the answer
Answer: was
In the past tense, use was because the grammatical subject is one, not packages.
Recognize the Reduced Preposition in Connected Speech
Native speakers rarely pronounce the word of with a strong vowel in spontaneous conversation. Instead, of weakens to a quick schwa sound followed by a soft v, sounding like /əv/. Before consonants, the v sound may even disappear almost entirely, leaving a short /ə/. Because the preposition is unstressed and spoken quickly, you should train your ear to catch the stressed number one at the start of the phrase.
-
One of our guests left an umbrella in the lobby.
Why it works: In natural speech, of our links smoothly as /wʌn əv aʊər/.
-
One of the doors is locked from the outside.
Why it works: The phrase one of the sounds like /wʌn əv ðə/, with stress on one and doors.
Your turn
How does the preposition of usually sound in natural, rapid speech before the word the?
Answer: It reduces to a short, unstressed sound like /əv/.
Show the answer
Answer: It reduces to a short, unstressed sound like /əv/.
In connected speech, of weakens to an unstressed schwa sound (/əv/) so speakers can emphasize key content words.
Separate the Relative Clause from the Main Sentence
A relative clause after one of the plus a plural noun can describe the group. In that reading, use a plural verb in the relative clause, while the main verb agrees with one. Identify what the relative clause describes instead of automatically choosing the nearest noun. If a different reading would be confusing, rewrite the sentence to make the reference clear.
-
One of the proposals that were submitted looks very promising.
Why it works: Were agrees with proposals inside the clause, while looks agrees with one.
-
She is one of the doctors who work at the regional clinic.
Why it works: Work is plural because who refers to doctors, not an individual.
Your turn
The relative clause describes the plural policies. Choose its verb: This is one of the policies that ___ employee safety.
Answer: protect
Show the answer
Answer: protect
The relative pronoun that describes policies, so the verb inside that clause takes the plural form protect.
Spot the Shift When Using the Only One
When speakers add the word only in front of one, the grammatical logic changes completely. The phrase the only one emphasizes that a single unique item possesses the quality, while the rest of the group does not. Because the relative clause now points directly to that solitary item, the verb inside the relative clause must be singular. Compare one of the items that work with the only one of the items that works.
-
He is the only one of our employees who speaks Japanese.
Why it works: Speaks is singular because the only one specifies a single person.
-
This is the only one of the printers that functions properly.
Why it works: Functions is singular because only one printer operates correctly.
Your turn
Choose the correct verb for this sentence: This is the only one of the laptops that ___ charged.
Answer: is
Show the answer
Answer: is
Because the phrase includes the only one, the relative clause describes that single item and takes the singular verb is.

Questions about "One of the Examples Is: Choosing Verbs"
Why do we use is instead of are after one of the examples?
The grammatical subject of the sentence is the word one, which refers to a single individual thing. The phrase of the examples is a prepositional phrase that describes the group from which that single item comes. Because verbs agree with their grammatical subjects rather than nearby prepositional nouns, you must use a singular verb like is, was, or has.
One of the examples is clear.
One of the examples was missing from the board.
Can I say one of the example instead of one of the examples?
Use one of the examples. The pattern one of the is followed by a plural count noun to name the set. The word one identifies a single member of that set. Learn the construction as a phrase rather than trying to justify it with a mathematical rule.
One of the students has finished early.
One of the cars is parked outside.
How do I choose the verb in one of the books that are or is?
Look at what the clause that describes. In one of the books that are popular, the relative clause describes the books in general, so that refers to books and takes the plural verb are. The main sentence verb still agrees with one, as in one of the books that are popular is on my desk.
One of the books that are popular is on my desk.
She is one of the doctors who work at the clinic.
Why does the only one of change the verb in a relative clause?
The phrase the only one highlights a single unique item rather than the plural group. In the only one of the books that is missing, the relative clause describes that single unique book. Because the focus shifts entirely to the singular item, the verb inside the relative clause becomes singular.
He is the only one of the applicants who meets every requirement.
This is the only one of the boxes that is damaged.
Before you go
Remember this
Remember that one is the grammatical subject of the main clause, requiring is, was, or has. Keep the group noun plural after of. When a relative clause describes the plural set, use a plural verb inside that clause, unless the phrase the only one specifies a single item.
