“Overlaps” and “overlap with” are both correct, but they do not work in exactly the same grammatical way.
The confusion usually comes from comparing a single verb form—overlaps—with a verb-plus-preposition construction—overlap with.
For example:
- The two schedules overlap.
- The two schedules overlap with each other.
- The evening class overlaps with my work schedule.
- The two research areas overlap.
The important point is that “overlaps” is normally the third-person singular present form of “overlap,” while “overlap with” is a construction in which “overlap” is followed by the preposition “with.”
The correct choice depends on the subject, sentence structure, and what you want to say.
This guide explains overlaps vs overlap with in simple terms, including grammar, meaning, sentence patterns, professional writing, academic English, everyday conversation, common mistakes, and more than 20 original examples.
Quick Answer
“Overlaps” is correct when the subject is singular and the verb is in the present tense: “The course overlaps with another class.”
“Overlap with” is used when overlap needs a following with phrase: “The course overlaps with another class.”
They are not always alternatives. “Overlaps” can stand alone, while “overlap with” explicitly introduces the other thing that shares space, time, features, or content.
Overlaps vs Overlap With: Comparison Table
| Feature | Overlaps | Overlap with |
|---|---|---|
| Basic form | overlaps | overlap with |
| Main grammatical role | Verb form or plural noun | Verb + preposition |
| Verb form | Third-person singular present | Base form of the verb + with |
| Subject | He, she, it, or singular noun | I, you, we, they, or plural noun; also after modal/auxiliary verbs |
| Meaning | To partly coincide, cover, or share something | To partly coincide or share something with another thing/person |
| Example | The topics overlap. / The topic overlaps another topic. | The topic overlaps with another topic. |
| Can “with” follow it? | Yes: overlaps with | Already included |
| Can it stand without “with”? | Yes, depending on construction | No, if you are specifically using the “overlap with” construction |
| Formality | Neutral | Neutral |
| Academic use | Very common | Very common |
| Business use | Common | Common |
| Everyday English | Common | Common |
| US vs UK | Both used | Both used |
| Common mistake | Using overlaps with the wrong subject | Using overlap with when the subject requires overlaps with |
| Easy example | The meetings overlap. | My meeting overlaps with yours. |
Quick rule: Don’t decide between these expressions based only on which one “sounds better.” First check the subject and sentence structure.
What Does “Overlaps” Mean?
Overlaps is the third-person singular present-tense form of the verb overlap.
It is used with a singular subject such as:
- he
- she
- it
- this
- that
- the meeting
- the course
- the schedule
- the idea
- the two-dimensional shape
For example:
The meeting overlaps with my lunch break.
Here, meeting is singular, so the verb becomes overlaps.
Compare:
- The meeting overlaps with my class.
- The meetings overlap with my classes.
The first sentence uses overlaps because meeting is singular. The second uses overlap because meetings is plural.
“Overlaps” Can Also Be a Noun
There is another important meaning of overlaps.
It can be the plural noun form of overlap:
There are several overlaps between the two proposals.
Here, overlaps is not a verb. It is a plural noun meaning areas of similarity, coincidence, or shared content.
Compare:
The subjects overlap.
Here, overlap is a verb.
There are several overlaps between the subjects.
Here, overlaps is a noun.
This distinction matters when someone searches for overlaps vs overlap with, because overlaps does not always function as a verb.
How “Overlaps” Works as a Verb
When overlaps is a verb, it describes something that partly coincides with, covers, or shares an area, period, feature, or subject.
Common patterns include:
Pattern 1: Subject + overlaps
The two plans overlap.
Notice that this sentence uses overlap, not overlaps, because plans is plural.
With a singular subject:
The plan overlaps with the existing proposal.
Pattern 2: Subject + overlaps + object
The verb overlap can also be used transitively in suitable contexts.
The new roof overlaps the old structure.
Here, the old structure is the direct object.
This construction can be perfectly grammatical, although the overlaps with construction is often a natural choice when the relationship between two things is being emphasized.
Pattern 3: Subject + overlaps with + noun
This is one of the most useful patterns:
The new policy overlaps with existing regulations.
The structure is:
Subject + overlaps + with + noun
For example:
- The course overlaps with another class.
- Her research overlaps with mine.
- The holiday overlaps with the school term.
- The project overlaps with our current work.
What Does “Overlap With” Mean?
Overlap with means that one thing partly coincides, shares features, or occupies some of the same space or time with another thing.
The word with establishes the relationship between the two things.
For example:
My appointment overlaps with your appointment.
The two appointments occur during some of the same time.
Another example:
Her research overlaps with my research.
The two areas share some subject matter.
The meaning of overlap with can therefore involve several kinds of similarity or coincidence.
Time
The two meetings overlap with each other.
They happen during some of the same period.
Physical Space
The two circles overlap with each other.
Part of one circle occupies the same area as part of the other.
Ideas
His argument overlaps with the main point of the report.
The ideas share some common ground.
Subjects
Biology overlaps with environmental science in several areas.
The subjects have some shared content.
Responsibilities
Her responsibilities overlap with those of the project manager.
Some duties are shared or similar.
Is “Overlap With” a Phrasal Verb?
Not usually.
This is an important grammar point.
Overlap with is better understood as a verb followed by the preposition “with.”
Compare it with classic phrasal verbs such as:
- give up
- take off
- look after
- turn down
In overlap with, the word with introduces the thing that overlaps.
So:
The two subjects overlap with each other.
Here, with retains its ordinary prepositional function.
Calling every verb followed by another word a “phrasal verb” can create unnecessary confusion.
Overlaps vs Overlap With: The Main Difference
The biggest difference is grammar, not basic meaning.
Consider these sentences:
The schedules overlap.
My schedule overlaps with yours.
The first sentence simply tells us that the schedules have a period in common.
The second explicitly tells us what the schedule overlaps with.
Now look at the singular subject:
The schedule overlaps with yours.
You cannot write:
The schedule overlap with yours.
That is a subject-verb agreement error.
Likewise, you normally cannot write:
My schedules overlaps with yours.
Because schedules is plural, the verb should be:
My schedules overlap with yours.
The Simple Formula
For present-tense statements:
Singular subject → overlaps
Plural subject → overlap
Examples:
- The class overlaps with the workshop.
- The classes overlap with the workshops.
- The schedule overlaps with mine.
- The schedules overlap with mine.
Grammar: Why the Verb Changes
The difference becomes much easier once you understand subject-verb agreement.
Singular Subject
Use overlaps:
The meeting overlaps with another meeting.
This topic overlaps with the previous chapter.
Her work overlaps with ours.
Plural Subject
Use overlap:
The meetings overlap with each other.
These topics overlap with the previous chapters.
Their responsibilities overlap with ours.
“I” and “You”
Use overlap, not overlaps:
I overlap with the other team on this project.
You overlap with her in several areas of expertise.
“He,” “She,” and “It”
Use overlaps:
He overlaps with the other consultant on several responsibilities.
She overlaps with another researcher.
It overlaps with the scheduled maintenance period.
What Happens With Modal Verbs?
After modal verbs such as can, may, might, should, will, could, and would, use the base form overlap, not overlaps.
Correct:
The meetings may overlap.
Incorrect:
The meetings may overlaps.
Correct:
The two subjects can overlap.
Incorrect:
The two subjects can overlaps.
Correct:
The new project will overlap with the existing project.
Incorrect:
The new project will overlaps with the existing project.
Why?
A modal verb takes the base form of the following verb:
may + overlap
can + overlap
will + overlap
should + overlap
Not:
may + overlaps
What Happens in the Past Tense?
The past form is simply overlapped.
Examples:
The two meetings overlapped.
The conference overlapped with the holiday.
Her presentation overlapped with mine.
The subject does not change the past-tense form:
- I overlapped
- you overlapped
- he overlapped
- she overlapped
- they overlapped
What Happens in the Progressive Tense?
Use overlapping after a form of be:
The two events are overlapping.
The meetings were overlapping.
The course is overlapping with another course.
Again, overlaps is not used after is/are/was/were in this construction.
Incorrect:
The meetings are overlaps.
Correct:
The meetings are overlapping.
What Happens in Questions?
Questions often make the difference especially clear.
Present Simple
For a singular subject:
Does the meeting overlap with another event?
Not:
Does the meeting overlaps with another event?
For a plural subject:
Do the meetings overlap with another event?
Not:
Do the meetings overlaps with another event?
The auxiliary does already carries the third-person singular marking, so the main verb returns to its base form:
Does + overlap
not
Does + overlaps
What Happens in Negative Sentences?
The same rule applies.
Correct:
The meeting doesn’t overlap with another class.
Not:
The meeting doesn’t overlaps with another class.
Correct:
The meetings don’t overlap with each other.
Not:
The meetings don’t overlaps with each other.

Common Mistakes With “Overlaps” and “Overlap With”
Mistake 1: Using “overlaps” After “does”
Wrong:
Does the meeting overlaps with your class?
Why it is wrong:
The auxiliary does already marks the third-person singular present tense. The main verb must be in its base form.
Correct:
Does the meeting overlap with your class?
Mistake 2: Using “overlaps” With a Plural Subject
Wrong:
The meetings overlaps with each other.
Why it is wrong:
Meetings is plural.
Correct:
The meetings overlap with each other.
Mistake 3: Using “overlap” With a Singular Subject
Wrong:
The meeting overlap with another event.
Correct:
The meeting overlaps with another event.
Mistake 4: Adding “-s” After a Modal
Wrong:
The two events may overlaps.
Correct:
The two events may overlap.
Mistake 5: Thinking “Overlap With” Is Always Required
Not every sentence needs with.
For example:
The two schedules overlap.
This is complete and natural.
You do not have to write:
The two schedules overlap with each other.
The longer version is possible, but the shorter version may be more efficient.
Mistake 6: Assuming “Overlap With” Is More Correct
Some writers assume that because they are talking about two things, they must use with.
That’s not true.
Both structures can be grammatical:
The two subjects overlap.
The two subjects overlap with each other.
The first is concise. The second explicitly highlights the relationship.
Mistake 7: Confusing “Overlaps” With the Plural Noun
Compare:
The two theories overlap.
Overlap = verb.
But:
There are several overlaps between the theories.
Overlaps = plural noun.
This is a completely different grammatical use.
When Should You Use “Overlaps”?
Use overlaps when:
- The subject is singular.
- You are using the present simple.
- You are not using a helping verb such as does, can, may, or will before it.
- You are describing one thing that overlaps something else or has an overlapping relationship.
Examples:
The meeting overlaps with my appointment.
This chapter overlaps with the previous one.
Her expertise overlaps with his.
The design overlaps the border.
When Should You Use “Overlap With”?
Use overlap with when you want to identify the other thing involved in the overlap and the grammar calls for the base form overlap.
Examples:
The two subjects overlap with each other.
My schedule does not overlap with yours.
The projects may overlap with one another.
Their research will overlap with ours.
Notice that overlap with can appear with singular subjects too—but when the singular subject is in a simple present affirmative sentence, it becomes overlaps with.
So these are both possible:
The course overlaps with another class.
The courses overlap with other classes.
The preposition with stays the same. The verb changes according to the subject.
Does “Overlaps With” Mean Something Different From “Overlaps”?
Usually, the central meaning is the same: two things have some shared area, time, content, characteristics, or relationship.
The difference is mainly one of sentence structure and emphasis.
Compare:
The meetings overlap.
This emphasizes the fact that they have a shared time period.
The meeting overlaps with the training session.
This identifies the other event involved.
Another example:
Their research overlaps.
This can be understood from context, but it does not specify the other research.
Their research overlaps with ours.
This clearly identifies the comparison.
A Useful Principle
“Overlap” can describe the relationship by itself. “Overlap with” lets you name the thing involved in that relationship.
That is why both forms are useful.
Professional and Academic Writing
Both forms are appropriate in professional and academic English.
In Business Writing
You might write:
The proposed duties overlap with the responsibilities of the existing team.
This is clear because the reader can immediately see what is being compared.
You could also write:
The proposed duties overlap considerably.
That version works when the context already makes the comparison clear.
In Academic Writing
The verb is particularly useful when discussing related concepts:
The two theoretical approaches overlap in their treatment of social interaction.
Or:
This framework overlaps with several existing models.
The choice depends on whether you need to name the other element.
In Formal Reports
Prefer the construction that communicates the relationship most precisely:
The implementation period overlaps with the final testing phase.
This is usually clearer than simply saying:
The implementation period overlaps.
The second sentence leaves the reader asking, “Overlaps with what?”
Tip: In professional writing, don’t add with automatically. Add it when the relationship needs to be stated explicitly.
“Overlap” vs “Overlap With” vs “Overlaps With”
A useful way to think about all three forms is:
| Form | Example | Why? |
|---|---|---|
| overlap | The schedules overlap. | Base/plural present form |
| overlaps | The schedule overlaps with mine. | Third-person singular present |
| overlap with | The schedules overlap with mine. | Base form + preposition |
| overlaps with | The schedule overlaps with mine. | Third-person singular + preposition |
| overlapped | The schedules overlapped. | Past tense |
| overlapping | The schedules are overlapping. | -ing form |
This is why comparing only “overlaps” and “overlap with” can be misleading.
In many sentences, the actual choice is determined by subject-verb agreement.
US vs UK English
There is no major American-versus-British distinction between overlaps and overlap with.
Both forms are standard in:
- American English
- British English
- Canadian English
- Australian English
- other varieties of standard English
The grammatical rules are essentially the same.
For example, both American and British writers can naturally say:
The two meetings overlap.
And:
The meeting overlaps with another event.
Differences may appear in the surrounding vocabulary or preferred style, but overlaps vs overlap with is not primarily a US-vs-UK issue.
Pronunciation
Overlaps
In American English, overlaps is commonly pronounced approximately:
oh-ver-LAPS
IPA: /ˌoʊvərˈlæps/
In British English, it is approximately:
oh-vuh-LAPS
IPA: /ˌəʊvəˈlæps/
Overlap With
Overlap with is pronounced approximately:
oh-ver-LAP with
The pronunciation of overlap does not change just because with follows it.
The important distinction is grammatical, not phonetic.
Common Collocations With “Overlap”
English speakers frequently use overlap with words connected to time, space, ideas, work, and responsibilities.
Common combinations include:
- overlap with
- overlap in
- overlap between
- partially overlap
- significantly overlap
- substantially overlap
- considerably overlap
- slightly overlap
- areas of overlap
- considerable overlap
- some overlap
- little overlap
- no overlap
Examples:
The two courses overlap in content.
There is considerable overlap between the two studies.
Their responsibilities overlap significantly.
The two schedules partially overlap.
These patterns are useful because they show that overlap is not limited to overlap with.
Noun vs Verb: Another Important Distinction
The word family can create confusion.
Verb
The two departments overlap.
Third-Person Singular Verb
The department’s responsibilities overlap with ours.
Actually, note that responsibilities is plural here, so the verb remains overlap.
With a singular noun:
The department’s role overlaps with ours.
Noun
There is significant overlap between the departments.
Plural Noun
There are several overlaps between the proposals.
Adjective/Participle
The overlapping responsibilities created confusion.
Understanding these forms helps prevent errors far beyond the specific phrase overlaps vs overlap with.
Memory Tricks
Here are a few simple ways to remember the difference.
Trick 1: Check the Subject
Ask:
Is the subject singular?
If yes, in a simple present affirmative sentence, use:
overlaps
The meeting overlaps.
If the subject is plural:
overlap
The meetings overlap.
Trick 2: “Does” Takes the “S”
Remember:
Does the meeting overlap?
Not:
Does the meeting overlaps?
Think:
DOES already has the S → don’t give the S to overlap.
Trick 3: Modals Use the Base Form
After:
- can
- could
- may
- might
- should
- will
- would
- must
use:
overlap
It may overlap.
Not:
It may overlaps.
Trick 4: “With” Names the Partner
Think of with as introducing the other side:
A overlaps with B.
For example:
The course overlaps with another course.
That makes overlap with easy to recognize.
A Fast Decision Guide
When you’re unsure which form to use, follow these steps.
- Find the subject.
- Ask whether the subject is singular or plural.
- Check whether another auxiliary verb comes before overlap.
- Decide whether you need to identify the other thing.
- Add with when the sentence calls for that construction.
For example:
The schedule ___ with my appointment.
Subject = schedule → singular.
No auxiliary verb.
Therefore:
The schedule overlaps with my appointment.
Now:
The schedules ___ with my appointments.
Subject = schedules → plural.
Therefore:
The schedules overlap with my appointments.
Now:
Does the schedule ___ with my appointment?
Because does is already present:
Does the schedule overlap with my appointment?
FAQs
Is “overlaps with” grammatically correct?
Yes. “Overlaps with” is grammatically correct when a singular third-person subject is followed by the preposition with.
The meeting overlaps with another event.
Is “overlap with” grammatically correct?
Yes. “Overlap with” is correct with plural subjects, with I/you, and after auxiliary or modal verbs.
The meetings overlap with each other.
The two projects may overlap with one another.
Should I say “overlaps” or “overlap with”?
It depends on the sentence. They are not interchangeable in every grammatical position.
The two schedules overlap.
But:
The schedule overlaps with mine.
The subject and sentence structure determine the form.
Is “overlaps” a noun or a verb?
It can be either.
As a verb:
The topics overlap.
As a plural noun:
There are several overlaps between the topics.
Context determines which meaning applies.
Is “overlap with” more formal than “overlap”?
No. Neither is inherently more formal.
Both are standard and suitable for everyday, professional, and academic English.
Is “overlaps with” correct in academic writing?
Yes. It is common when discussing shared ideas, methods, research areas, theories, themes, or findings.
The study overlaps with previous research in several respects.
Can I say “the two things overlap with each other”?
Yes, although “the two things overlap” is often more concise.
The two designs overlap.
The two designs overlap with each other.
Both can be grammatical, but the second explicitly expresses the relationship.
Is “overlaps” American English and “overlap with” British English?
No. This is not a US-vs-UK distinction. Both constructions are used in both varieties of English.
What is the easiest rule for “overlaps vs overlap with”?
Remember:
Singular subject + present simple = overlaps
Plural subject + present simple = overlap
And if you identify the other thing involved, with may follow:
The meeting overlaps with the class.
Final Verdict
The answer to “overlaps vs overlap with” is not that one is correct and the other is wrong. Both are legitimate English forms, but they serve different grammatical roles.
Use overlaps when the subject is singular and you are using the third-person singular present form:
The meeting overlaps with my class.
Use overlap with when overlap needs its base form—for example, after a modal, auxiliary, or with a plural subject:
The meetings overlap with each other.
The meetings may overlap with another event.
You can also use overlap without with when the context already makes the relationship clear:
The two schedules overlap.
The most important lesson is this:
Don’t treat “overlaps” and “overlap with” as two competing vocabulary choices. Check the grammar of the sentence first.
For everyday, business, and academic English, the best form is the one that matches the subject, verb structure, and intended relationship. When you need to specify what something coincides with, overlap with is often the clearest construction. When the comparison is already obvious, overlap can be shorter and more natural.
