If you are looking for a during synonym, the best alternative depends on what you mean by during.
Common alternatives include in, throughout, over, in the course of, at the time of, and amid, while while is often the natural choice when a clause follows. However, these words are not interchangeable in every sentence.
During normally introduces a noun or noun phrase referring to a period or event, whereas while introduces a clause. Choosing the right alternative therefore depends on grammar, duration, formality, and context.
Quick Answer: What Is a Synonym for During?
The most useful alternatives to during are:
| Alternative | Best use | Example |
| in | A period, season, year, or historical era | We met in the summer. |
| throughout | The whole of a period | It rained throughout the night. |
| over | A period in which something develops or happens | Sales increased over the year. |
| in the course of | Formal or professional writing | Several changes occurred in the course of the project. |
| at the time of | A specific event or historical point | He was abroad at the time of the accident. |
| while | Before a clause with a subject and verb | She called while I was working. |
| amid | Something happening in an atmosphere or surrounding situation | The decision came amid growing concern. |
| through | Continuing from one point to another, especially in informal usage | We worked through the night. |
The closest replacement is not always the most natural one. For example, throughout emphasizes the whole period, while in often simply identifies the period. While is structurally different because it normally introduces a clause.
What Does During Mean?
During is a preposition used to indicate when something happens in relation to a period or event.
It can mean either:
- At some point within a period
- We received the news during the afternoon.
- Throughout or over the course of a period
- She remained calm during the interview.
Cambridge explains that during can refer to the whole period or to an unspecified point within that period.
Pronunciation
In American English, during is pronounced approximately /ˈdʊrɪŋ/. British English commonly uses /ˈdjʊərɪŋ/.
The stress falls on the first syllable.
During Synonyms by Meaning and Context
There is no single replacement that works everywhere. Think of the alternatives as a semantic ladder:
during → in → over → throughout → in the course of → at the time of → while
The closer you move toward the right, the more the grammatical structure or emphasis can change.
1. In
In is one of the most natural alternatives when during identifies a broad period.
Meaning: at some point within a specified period.
Tone: neutral
Formality: neutral
Best contexts: everyday English, academic writing, professional communication
Examples:
- We visited them during the summer.
- We visited them in the summer.
- The company expanded during 2025.
- The company expanded in 2025.
However, in does not always carry exactly the same emphasis. During can emphasize the occurrence of an event within a period, while in often simply places the event in that period.
2. Throughout
Throughout is particularly useful when you want to emphasize that something continued across the whole period.
Meaning: from beginning to end, or at all points within a period.
Tone: neutral to emphatic
Formality: neutral
Best contexts: formal writing, reports, narratives, academic English
Examples:
- She remained focused during the meeting.
- She remained focused throughout the meeting.
The second sentence more strongly suggests that her focus was maintained for the entire meeting.
Common collocations
- throughout the year
- throughout the day
- throughout the night
- throughout the process
- throughout the project
- throughout the period
Key distinction:
Use during when you simply identify when something happened. Use throughout when the idea of the whole period matters.
3. Over
Over can describe something happening across a period, particularly when discussing change, development, comparison, or trends.
Examples:
- The population increased during the decade.
- The population increased over the decade.
- Her confidence improved during the course.
- Her confidence improved over the course of the course.
Best contexts:
- business reports
- statistics
- research
- trends
- personal development
- historical change
Common expressions include:
- over time
- over the years
- over the course of a year
- over the weekend
- over the next few months
Nuance: over often makes a period feel like a span across which something develops.
4. In the Course of
In the course of is a formal phrase meaning during the development or progression of something.
Formality: formal
Best contexts: academic writing, legal writing, business reports, professional communication
Examples:
- Several problems emerged in the course of the investigation.
- The company changed its strategy in the course of the negotiations.
It is usually more elaborate than during, so replacing during with in the course of can make a sentence sound unnecessarily formal in casual conversation.
Compare
Simple:
We discovered the problem during the investigation.
Formal:
We discovered the problem in the course of the investigation.
Both are grammatical, but the second gives the sentence a more formal register.
5. At the Time of
At the time of is useful when referring to a specific event or historical circumstance.
Examples:
- She was living abroad at the time of the accident.
- He was the company director at the time of the merger.
It is especially useful when during feels too broad.
During vs At the Time of
During the incident emphasizes the period in which something happened.
At the time of the incident emphasizes the particular point or circumstances surrounding the incident.
This distinction can matter in historical, legal, journalistic, and professional writing.
6. While
While is one of the most important alternatives to during, but it is not grammatically interchangeable in every sentence.
Use during + noun/noun phrase:
I listened to music during the flight.
Use while + clause:
I listened to music while I was flying.
Cambridge identifies while as a conjunction meaning “during the time that” and notes that it normally connects a clause.
During vs While
| During | While |
| Preposition | Conjunction |
| Followed by a noun phrase | Usually followed by subject + verb |
| during the meeting | while we were meeting |
| during dinner | while we were eating dinner |
| during the journey | while we were traveling |
Common mistake:
❌ During I was studying, my phone rang.
✅ While I was studying, my phone rang.
This is one of the most important grammar rules to remember.
7. Amid
Amid means surrounded by or occurring in the middle of a particular situation, condition, or atmosphere.
Examples:
- The announcement came during growing criticism.
- The announcement came amid growing criticism.
The second sentence does more than identify time: it creates a sense of surrounding circumstances.
Best contexts:
- journalism
- formal writing
- political reporting
- business writing
- literary prose
During vs Amid
During = when something happened.
Amid = the circumstances surrounding something when it happened.
Therefore, amid is a contextual alternative rather than a universal synonym.
8. Through
Through can sometimes replace during when the meaning involves continuing across a period.
Examples:
- We worked during the night.
- We worked through the night.
The second version often suggests continuation from one part of the night toward another or across the night.
It is especially common in expressions such as:
- through the night
- through the winter
- through the difficult period
It should not automatically replace during in every sentence.

During vs Related Words: The Important Differences
During vs While
During takes a noun phrase:
during the meeting
While normally takes a clause:
while we were meeting
Choose while when you want to express two actions or situations occurring at the same time.
During vs Throughout
These overlap, but throughout more strongly emphasizes the complete period.
He stayed quiet during the meeting.
This tells us when he stayed quiet.
He stayed quiet throughout the meeting.
This suggests that his silence continued across the entire meeting.
During vs In
These are often interchangeable with periods such as:
- the summer
- the year
- the 1990s
- the war
Examples:
Many changes occurred during the 1990s.
Many changes occurred in the 1990s.
The choice is often stylistic and contextual rather than a major difference in meaning.
During vs Over
During focuses on when something occurred.
Over often focuses on development or change across a span.
She improved during the program.
She improved over the course of the program.
The second sentence naturally highlights progression.
During vs For
This is a particularly important distinction.
During identifies when something happens.
For identifies how long something lasts.
Compare:
We traveled during the summer.
This identifies the period.
We traveled for three weeks.
This gives the duration.
Common mistake
❌ We stayed there during three weeks.
✅ We stayed there for three weeks.
Cambridge specifically advises using for rather than during with ordinary expressions of numerical duration such as “three weeks” or “two hours.”
During Synonym Decision Matrix
When choosing a replacement, ask what you want the sentence to emphasize.
| If you want to emphasize… | Consider |
| A general time period | during / in |
| The entire period | throughout |
| Development across time | over |
| A formal process | in the course of |
| A specific historical/event context | at the time of |
| Two simultaneous actions | while |
| Surrounding circumstances | amid |
| Continuation across a period | through |
| Duration | for |
This matrix is more useful than memorizing a flat list because it connects vocabulary choice to meaning.
During: Grammar Rules You Should Know
Rule 1: Use during before a noun or noun phrase
✅ during the meeting
✅ during the summer
✅ during the examination
✅ during my childhood
Rule 2: Do not normally put a finite clause directly after during
❌ during I was studying
✅ while I was studying
Rule 3: Do not use during for ordinary numerical duration
❌ during two hours
✅ for two hours
Rule 4: “During” can refer to a whole period or an unspecified point within it
I slept during the flight.
This does not necessarily mean that I slept continuously from takeoff to landing.
I worked throughout the flight.
This more strongly suggests the entire period.
Cambridge explicitly distinguishes these uses.

Common Mistakes With During
Mistake 1: Confusing during with for
❌ I studied during three hours.
✅ I studied for three hours.
Mistake 2: Using during before a verb clause
❌ During I was driving, she called.
✅ While I was driving, she called.
Mistake 3: Assuming throughout always means during
Although the meanings overlap, throughout adds a stronger whole-period meaning.
Mistake 4: Replacing every instance of during with while
Not every noun phrase can simply be converted without changing sentence structure.
❌ I met him while the conference.
✅ I met him during the conference.
Or:
✅ I met him while the conference was taking place.
Mistake 5: Using a more formal synonym when it adds no value
“In the course of” may be grammatically correct, but during is often clearer and more concise.
Vocabulary Ladder: From Simple to Sophisticated
For vocabulary development, consider these choices as a register ladder:
Basic / everyday:
during, in, while
Neutral / polished:
throughout, over
Formal:
in the course of, at the time of
Contextual / literary:
amid, through
The most sophisticated word is not automatically the best word. Strong writing uses the word that communicates the intended relationship with the least unnecessary complexity.
How to Choose the Best During Synonym
Use this five-question decision process:
1. Is the following word a noun or noun phrase?
If yes, during, in, throughout, or over may work.
2. Is the following structure a subject + verb?
Consider while.
3. Do you mean the entire period?
Consider throughout.
4. Are you describing change across a period?
Consider over.
5. Are you emphasizing surrounding circumstances rather than time alone?
Consider amid.
This produces more precise writing than simply replacing during with the first synonym found in a thesaurus.
Frequently Asked Questions About During Synonyms
What is the closest synonym for during?
The closest alternative depends on context. In can often replace during with periods such as years, seasons, and eras. Throughout is closer when the whole period is emphasized, while while is appropriate when a clause follows.
What is another word for during?
Common alternatives include in, throughout, over, while, in the course of, at the time of, amid, and through. They differ in grammar and meaning, so they are not universally interchangeable.
Can I use while instead of during?
Often, yes, but the grammar usually changes. Use during + noun phrase and while + clause.
during the meeting
while we were meeting
Is throughout a synonym for during?
Throughout overlaps with during but usually emphasizes that something continues across the whole period.
It rained during the day.
It rained throughout the day.
The second sentence more strongly suggests continuous or repeated occurrence across the entire day.
Is “in” a synonym for during?
In many time expressions, yes.
during the summer
in the summer
during 2025
in 2025
However, in and during can differ in emphasis depending on the sentence.
Is “for” a synonym for during?
No. For normally expresses duration, while during identifies the period when something happens.

We visited during the summer.
What is the formal synonym of during?
Depending on context, in the course of and at the time of can provide more formal alternatives. Throughout is also appropriate when the whole period is intended.
What is the best synonym for during in academic writing?
There is no single best replacement. During is already appropriate in academic writing. Throughout works when the entire period matters, while over is useful for developments or changes across time.
Final Takeaway
The most important lesson about during synonyms is that synonymy is not simply a matter of replacing one word with another.
Use during when you want a clear, neutral way to identify when something happens. Choose in for many broad time periods, throughout when the whole period matters, over when development across time is important, while when a clause follows, in the course of for formal process-oriented writing, at the time of for specific events, and amid when surrounding circumstances are part of the meaning.
For natural English, precision matters more than variety. Replacing during just to avoid repetition can make writing less clear. A strong vocabulary choice is the one that matches the intended time relationship, grammar, register, and context.
That is why understanding the meaning and function of each alternative is more valuable than memorizing a long synonym list.
