“It Takes Two to Make a Quarrel or Battle – Meaning & Origin” explains how both parties shape a disagreement, conflict, or quarrel and its outcome.
The saying highlights mutual participation: one person may start an argument, but a real quarrel usually continues only when the other person chooses to engage. If someone stays calm, refuses to argue back, or decides not to participate, the conflict can lose its momentum.
In this sense, the proverb connects everyday communication with the choices people make during disputes.The idea is easy to understand through a shared project between two friends. Imagine that one friend becomes upset and starts arguing about how the work should be completed.
Quick Answer: “In the Morning” or “On the Morning”?
Use “in the morning” when you’re talking about the morning as a general period of the day, especially for routines, habits, or an unspecified time.
I usually read in the morning.
Use “on the morning of” when you’re referring to a specific morning connected to a particular date, day, or event.
We arrived on the morning of the wedding.
You can also say “on Monday morning,” “on Friday morning,” or “on July 4 in the morning” when a specific day or date identifies the morning.
| Expression | Main use | Example |
| in the morning | General or unspecified morning | I walk in the morning. |
| on Monday morning | Specific day | We met on Monday morning. |
| on the morning of the meeting | Specific event | She called me on the morning of the meeting. |
| this morning | Current/recent morning | I saw him this morning. |
| tomorrow morning | Following morning | I’ll call you tomorrow morning. |
| yesterday morning | Previous morning | She arrived yesterday morning. |
Cambridge Dictionary defines “in the morning” as referring to the early part of the day and also uses it for a period between midnight and noon.
What Does “In the Morning” Mean?
“In the morning” refers to the morning period without necessarily identifying one particular calendar morning.
Think of it as a broad time window. You’re telling someone when during the day something happens rather than pointing to a particular date.
For example:
- I drink coffee in the morning.
- She checks her email in the morning.
- We usually leave in the morning.
- He feels more productive in the morning.
- The store gets busy in the morning.
These sentences don’t identify a particular Monday, date, or event. They simply place the activity somewhere during morning hours.
“In the Morning” for Daily Routines
One of the most common uses involves habits and routines.
I go for a walk in the morning.
The sentence doesn’t mean one particular morning. It describes a regular habit.
You could also say:
She reads the newspaper in the morning.
Again, the focus is on her routine rather than a specific date.
This pattern works naturally with words such as usually, often, always, sometimes, every day, normally, and typically.
Examples
- I usually exercise in the morning.
- He often drinks tea in the morning.
- We normally have breakfast early in the morning.
- She always checks her calendar in the morning.
- They sometimes go running in the morning.
The broad time frame is what makes “in” sound natural.
“In the Morning” for an Unspecified Morning
The phrase can also refer to one morning without telling the listener exactly which morning.
For example:
I’ll call you in the morning.
Depending on the context, this often means the next morning. Cambridge specifically lists this meaning for “in the morning.”
Consider this conversation:
A: When will you send the report?
B: I’ll send it in the morning.
The speaker doesn’t need to say “tomorrow morning” because the context may already make the intended morning obvious.
What Does “On the Morning” Mean?
Here’s where things get interesting.
“On the morning” usually doesn’t work naturally as a complete phrase by itself when you simply mean morning in general.
Instead, “on” commonly appears when something makes the morning specific.
For example:
On the morning of the wedding, everyone arrived early.
The phrase “the wedding” identifies which morning you’re talking about.
Likewise:
On the morning of July 4, the streets were unusually quiet.
The date identifies the morning.
The key idea is specificity.
Why “On the Morning” Usually Needs More Information
If someone says:
I exercise in the morning.
The sentence sounds incomplete because the listener naturally expects more information.
You could instead say:
I exercise in the morning.
Or, if you’re talking about a particular occasion:
I exercised on the morning of the race.
That small change completely alters the structure.
“On the Morning of…” for Specific Events
The pattern “on the morning of + noun” is especially common in formal writing, news reports, historical accounts, and storytelling.
Examples include:
- on the morning of the wedding
- on the morning of the exam
- on the morning of the election
- on the morning of July 4
- on the morning of her departure
- on the morning of the conference
- on the morning of his arrival
For example:
On the morning of the exam, Maria woke up earlier than usual.
The phrase doesn’t describe mornings generally. It identifies one particular morning associated with the exam.
“In the Morning” vs. “On the Morning”: The Key Difference
The easiest way to remember the distinction is to ask yourself one question:
Am I talking about morning generally, or can I identify the particular morning?
If you’re speaking generally, choose in.
If you’re identifying a particular morning through a date, day, or event, it often fits.
| General reference | Specific reference |
| I study in the morning. | I studied on the morning of the exam. |
| She works in the morning. | She worked on Monday morning. |
| We exercise in the morning. | We exercised on the morning of the race. |
| He called in the morning. | He called on the morning of June 10. |
A useful mental shortcut is:
General morning → IN
Specific morning → ON
This follows the broader English pattern in which it often works with broader periods while on commonly marked specific days and dates. Cambridge’s examples include “Monday morning,” “Monday afternoon,” “Monday evening,” and “Monday night.”
Why Do We Say “In the Morning” but “On Monday Morning”?
This becomes much easier when you stop treating morning as the only important word.
Compare:
I exercise in the morning.
with:
I exercise on Monday morning.
In the first sentence, morning is simply a part of the day.
In the second, Monday identifies a specific day. The expression therefore follows the normal pattern for a particular day: on Monday.
The same structure appears with other days:
- on Tuesday morning
- on Wednesday morning
- on Thursday morning
- on Friday morning
- on Saturday morning
- on Sunday morning
For example:
We have a staff meeting on Monday morning.
Cambridge Dictionary specifically gives “Monday morning” as a standard expression and provides examples using it with on.
“On the Morning” vs. “On Monday Morning”
These expressions are related, but they aren’t identical in structure.
On Monday Morning
“On Monday morning” already contains the specific day.
I have a doctor’s appointment on Monday morning.
There’s no need to add on.
On the Morning of Monday
You can construct a phrase such as:
On the morning of Monday, June 8, the ceremony began.
However, when the day and date are already known, “on Monday morning” is usually more direct and natural.
For example:
We met on Monday morning.
is cleaner than:
We met on the morning of Monday.
When a formal date or event needs emphasis, however, “on the morning of…” can be useful:
On the morning of Monday, June 8, the committee released its report.
The important point isn’t that one structure is universally “better.” The choice depends on how specifically you need to identify the morning.
“In the Morning” vs. “On the Morning of” With Real Examples
The contrast becomes much clearer when the sentences sit side by side.
General Routine
I answer emails in the morning.
This describes a regular activity.
Specific Event
I answered the emails on the morning of the conference.
Now the morning belongs to a specific event.
General Habit
She likes to run in the morning.
No particular morning is identified.
Specific Date
She ran five miles on the morning of June 12.
The date pins the action to one particular morning.
General Future Plan
We’ll leave in the morning.
The exact morning may be understood from context.
Specific Occasion
We’ll leave on the morning of the wedding.
The wedding identifies the particular morning.
“This Morning,” “Tomorrow Morning,” and “Yesterday Morning”
Some morning expressions don’t need in or on at all.
That’s an important point because learners sometimes try to force a preposition into every expression.
This Morning
Say:
I saw him this morning.
Not:
I saw him this morning.
And normally not:
I saw him this morning.
This morning already functions as a complete time expression.
Tomorrow Morning
Say:
I’ll call you tomorrow morning.
Not:
I’ll call you tomorrow morning.
The word tomorrow already identifies the relevant day.
Yesterday Morning
Say:
She arrived yesterday morning.
Again, no additional preposition is needed.
Monday Morning
With a named weekday, on is standard:
She arrived on Monday morning.
This gives us four useful patterns:
| Time expression | Correct example |
| General | in the morning |
| Current day | this morning |
| Next day | tomorrow morning |
| Previous day | yesterday morning |
| Specific weekday | on Monday morning |
“In the Morning” vs. “On the Morning” in Formal Writing
Formal writing often uses “on the morning of” because writers need to establish a precise timeline.
For example:
On the morning of September 12, the committee met to discuss the proposal.
That sentence immediately establishes a particular date.
News writing and historical writing often need this kind of precision because the exact timing can matter.
By contrast:
The committee usually meets in the morning.
Here, the writer isn’t documenting one specific occasion. The sentence describes a general schedule.
Business Writing
The same distinction works in emails.
General:
I’ll review the document in the morning.
Specific:
I’ll review the document on the morning of the presentation.
The first sentence refers to a general upcoming time. The second connects the action to a particular event.

Common Mistakes With “In the Morning” and “On the Morning”
Mistake: Using “On the Morning” for General Habits
Incorrect:
I usually exercise in the morning.
Better:
I usually exercise in the morning.
The sentence describes a recurring habit rather than one identified morning.
Mistake: Using “In the Morning of” Before a Specific Date
A common learner construction is:
❌ In the morning of July 10, the team arrived.
For standard US English, the natural choice is:
✅ On the morning of July 10, the team arrived.
The distinction follows the relationship between the specific date and the morning being identified.
Mistake: Forgetting “The”
When using the event pattern, write:
on the morning of the meeting
not:
❌ on morning of the meeting
The noun morning normally takes the in this construction because you’re referring to a particular morning.
Mistake: Adding a Preposition to “Tomorrow Morning”
Don’t write:
❌ I’ll see you in tomorrow morning.
Write:
✅ I’ll see you tomorrow morning.
The same principle applies to this morning and yesterday morning.
“In a Morning” vs. “In the Morning”
The article changes the meaning.
In the Morning
“In the morning” normally refers to the morning period in general or to a contextually understood morning.
I like reading in the morning.
In a Morning
“In a morning” can refer to one unspecified morning.
For example:
It happened in a morning when the town was unusually quiet.
This construction is grammatically possible, but it’s less common in ordinary conversation than “in the morning.”
In everyday English, you’d often naturally say:
It happened one morning when the town was unusually quiet.
That’s a good example of how grammatical possibility and natural everyday usage aren’t always identical.
Can You Say “On a Morning”?
Yes, “on a morning” can occur, particularly when the writer describes a particular type of morning in a narrative or descriptive context.
For example:
On a cold winter morning, the hikers set out before sunrise.
Here, a cold winter morning identifies a particular morning in the story.
The structure is different from the everyday expression:
I work in the morning.
The first sentence presents a particular morning as part of a narrative. The second refers to morning as a general time period.
Prepositions With Other Parts of the Day
The same basic distinction appears beyond morning.
General Parts of the Day
We normally say:
- in the morning
- in the afternoon
- in the evening
Examples:
I work in the afternoon.
We usually eat dinner in the evening.
When the period becomes specific, on can appear:
on the afternoon of the ceremony
on the evening of July 4
This pattern mirrors on the morning of.
What About “At Night”?
Night behaves differently in ordinary English.
We commonly say:
I don’t like driving at night.
Not:
❌ I don’t like driving in the night.
However, “in the night” does occur in certain contexts, especially when referring to something happening during a particular night or in more literary language.
For everyday communication, at night is the normal expression.
A Simple Way to Remember the Rule
Imagine you’re using a camera.
“In the morning” gives you a wide-angle view. You know the activity happens during morning hours, but you don’t necessarily know which morning.
“On the morning of the wedding” zooms in. Now you’ve identified one particular morning.
That gives you this practical rule:
General morning = in the morning
Specific morning = on the morning of + date/event
Specific weekday = on + weekday + morning
For example:
- I study in the morning.
- I studied on Monday morning.
- I studied on the morning of the exam.
Once you see the difference as a matter of time specificity, the choice becomes much easier.
A Practical Decision Guide
When you’re unsure, follow these steps.
Ask: Is the Morning General?
If you’re talking about a routine or broad time period, use:
in the morning
I answer emails in the morning.
Ask: Is a Specific Day Named?
If you name Monday, Tuesday, or another specific day, use:
on + day + morning
We met on Tuesday morning.
Ask: Is a Specific Date or Event Named?
Use:
on the morning of + specific reference
We arrived on the morning of the ceremony.
Ask: Does the Expression Already Contain a Time Word?
If you’re using this, yesterday, or tomorrow, you generally don’t need a preposition.
This morning, I called her.
I’ll see you tomorrow morning.
We spoke yesterday morning.
Case Study: How One Preposition Changes the Sentence
Consider this pair:
I spoke to John in the morning.
This tells us that the conversation happened during the morning. The exact day isn’t specified by the sentence.
Now consider:
I spoke to John on the morning of the interview.
The second sentence identifies the particular morning through the interview.
The difference isn’t simply about choosing one preposition over another. The structure tells the reader how the time relates to the event.
This is why the phrase “on the morning of…” appears so often when writers describe particular events, dates, meetings, ceremonies, examinations, trips, and historical moments.

Conclusion
The choice between “in the morning” and “on the morning” depends mainly on whether you’re talking about morning generally or identifying a specific morning. Use “in the morning” for routines, habits, and broad references, such as “I exercise in the morning.” When a particular day, date, or event identifies the morning, use “on”, as in “We arrived on the morning of the wedding” or “We met on Monday morning.”
The easiest rule is to remember three patterns: in the morning for a general or unspecified morning, on + day + morning for a specific day, and on the morning of + date/event for a particular occasion. Expressions such as this morning, yesterday morning, and tomorrow morning normally don’t need a preposition. Once you understand this difference, choosing the correct expression becomes much easier and your English sounds more natural, precise, and confident.
