If you are looking for a then synonym, the best replacement depends on what then means in the sentence. Then it can refer to a time in the past, a sequence of events, a consequence, or a condition. Natural alternatives include afterward, next, later, subsequently, at that time, in that case, therefore, and at the time. Choosing the right word requires looking at the relationship between the ideas, not simply replacing one word with another.
Quick Answer: What Is a Synonym for Then?
Common alternatives to then include:
- Afterward — at a later time
- Next — immediately following something
- Later — at a subsequent time
- Subsequently — afterward, especially in formal writing
- At that time — referring to a particular past or future point
- After that — following a previously mentioned event
- Thereafter — from that point onward
- In that case — if the stated condition is true
- Therefore — for that reason, when then expresses a consequence
- So — as a result, in informal communication
The important point is that these words are not interchangeable in every sentence. The meaning of then determines which alternative sounds natural.
What Does “Then” Mean?
Then is a highly flexible adverb. Its meaning changes according to context, which is why finding a precise replacement can be surprisingly difficult.
It commonly performs four functions:
| Meaning of “then” | Example | Natural alternative |
|---|---|---|
| Past time | “I lived there then.” | at that time |
| Sequence | “We ate, then we left.” | afterward / next |
| Future consequence | “If you agree, then we can begin.” | in that case |
| Logical result | “If that is true, then we need evidence.” | therefore / in that case |
This makes then an example of a polysemous word: one spelling carries several related meanings.
The Then-Synonym Ladder
A useful way to select an alternative is to think of them as belonging to different semantic lanes rather than treating every synonym equally.
Time
Use these when they identify a point or period:
at that time → during that period → back then → at the time → previously
Example:
“She was living in London then.”
Possible rewrite:
“She was living in London at that time.”
Sequence
Use these when one event follows another:
next → afterward → after that → subsequently → thereafter
Example:
“He finished the report, then sent it to his manager.”
Natural alternatives:
“He finished the report and afterward sent it to his manager.”
“He finished the report and subsequently sent it to his manager.”
Condition or consequence
When then follows an if-clause, it often means something like in that case or as a consequence.
Example:
“If the figures are correct, then we need to reconsider the plan.”
Possible alternatives:
“If the figures are correct, in that case, we need to reconsider the plan.”
“If the figures are correct, therefore, we need to reconsider the plan.”
The second version changes the grammatical structure and can sound less natural in ordinary conversation.
25+ Useful Alternatives to Then
1. Afterward
Meaning: At a later point following an event.
Tone: Neutral
Formality: Neutral
Best contexts: Everyday writing, storytelling, personal communication.
Example:
“She called her mother and went home afterward.”
Difference from then: Afterward clearly emphasizes what happened later. It does not normally carry the conditional meaning of then.
Common collocations:
- shortly afterward
- immediately afterward
- soon afterward
2. Next
Meaning: Immediately following the current event or step.
Tone: Neutral
Formality: Neutral
Example:
“First, read the instructions. Next, complete the form.”
Best contexts: Instructions, processes, education, presentations, storytelling.
Next is more strongly associated with sequence than then.
3. Later
Meaning: At a subsequent time.
Tone: Neutral
Formality: Neutral
Example:
“I’ll explain the details later.”
Use later when the exact sequence matters less than the fact that something happens afterward.
4. Subsequently
Meaning: After a particular event or point.
Tone: Objective, professional
Formality: Formal
Example:
“The proposal was reviewed and subsequently approved.”
This is useful in reports, academic writing, legal documents, and professional summaries.
Avoid: Using subsequently in casual conversation where it would later or afterward would sound more natural.
5. After that
Meaning: Following the event just mentioned.
Tone: Conversational
Formality: Neutral
Example:
“We had dinner. Subsequently, we watched a movie.”
It is especially useful when clarity matters more than stylistic variety.
6. At that time
Meaning: During the particular period being discussed.
Example:
“I didn’t understand the decision at that time.”
This is one of the strongest alternatives when they refer to a specific period rather than sequence.
7. At the time
Meaning: During the period discussed.
Example:
“I didn’t know about the problem at the time.”
This expression often sounds more natural than then in explanatory prose.
8. Thereafter
Meaning: From that point onward or after that event.
Formality: Formal
Example:
“The agreement was signed, and the new policy took effect thereafter.”
It is common in legal, administrative, and formal writing but can sound overly stiff in everyday conversation.
9. From that point onward
Meaning: Beginning at a particular moment and continuing afterward.
Example:
“From that point onward, the team followed a different strategy.”
This is more explicit than then and is useful when duration matters.
10. In that case
Meaning: If the situation just described is true, this is what follows.
Example:
“If you already have the document, then you don’t need another copy.”
Rewrite:
“If you already have the document, in that case, you don’t need another copy.”
This is a conditional alternative, not a time-based synonym.
11. Therefore
Meaning: For that reason; consequently.
Formality: Neutral to formal
Example:
“The evidence was incomplete; therefore, the conclusion remained uncertain.”
Therefore can sometimes replace the logical function of then, but not its temporal meaning.
12. Consequently
Meaning: As a result of something.
Formality: Formal
Example:
“The deadline was missed. Consequently, the launch was postponed.”
This is appropriate when the relationship is cause → result.
13. Thus
Meaning: In this way or as a result.
Formality: Formal
Example:
“The evidence was insufficient, thus preventing a firm conclusion.”
Thus has several functions, so context determines whether it is actually an appropriate replacement.
14. So
Meaning: As a result or consequently.
Tone: Conversational
Example:
“If you’re ready, so we can begin.”
This example shows why direct substitution can fail. In many conditional constructions, then is more natural:
“If you’re ready, then we can begin.”
So it is usually better when it introduces a result:
“It was raining, so we stayed inside.”
15. Back then
Meaning: At that earlier time.
Tone: Informal
Example:
“Back then, we didn’t have smartphones.”
This is particularly natural when talking nostalgically about the past.
Then Synonyms by Context
Different writing situations call for different alternatives.
| Context | Best choices | Example |
|---|---|---|
| Casual conversation | later, afterward, next | “I’ll call you later.” |
| Storytelling | afterward, next, after that | “After that, they left.” |
| Academic writing | subsequently, thereafter | “The samples were subsequently analyzed.” |
| Business writing | subsequently, thereafter, at that point | “The agreement was subsequently revised.” |
| Legal writing | thereafter, at that time | “The parties thereafter agreed…” |
| Instructions | Next, afterward | “Next, select the appropriate option.” |
| Historical writing | at that time, during that period | “At that time, the region was under different rule.” |
| Informal nostalgia | back then | “Back then, things were simpler.” |
| Conditional reasoning | in that case | “If so, then we should proceed.” |
| Cause and effect | Therefore, consequently | “The evidence was weak; therefore, the claim was rejected.” |
Then vs. Next
Then and next both express sequences, but they are not identical.
“First, mix the ingredients. Then add the flour.”
“First, mix the ingredients. Next, add the flour.”
Both are natural.
The distinction is subtle: next often highlights the following step, while then can simply indicate what happened afterward.
For instructions, next is often particularly clear because it creates an obvious step-by-step progression.
Then vs. Later
These words are closely related but emphasize different ideas.
Then can describe a specific point in a sequence:
“We finished dinner, then went home.”
Later emphasizes a subsequent time:
“We went home later.”
If you need to communicate order, choose then. If you mainly need to communicate at a later time, later may be better.
Then vs. Afterward
Afterward means after a particular event.
“We discussed the problem and went for coffee afterward.”
Then is broader:
“We discussed the problem, then went for coffee.”
In many sentences, it either works. Afterward places slightly more emphasis on the fact that the second event occurred following the first.
Then vs. Subsequently
The difference is mostly one of register.
Then is ordinary and versatile:
“The committee reviewed the proposal, then approved it.”
Subsequently is more formal:
“The committee reviewed the proposal and subsequently approved it.”
For everyday communication, then is usually preferable. For formal reports, subsequently may fit the surrounding register.
Then vs. Therefore
These words should not normally be treated as direct synonyms.
Compare:
“He missed the train, then took a taxi.”
Here, then means afterward.
“He missed the train; therefore, he took a taxi.”
Here, therefore means because of that / as a result.
The first emphasizes sequence. The second emphasizes reason and consequence.
That distinction is important when editing formal writing.
Choosing the Right Alternative: A Decision Guide
When you want to replace them, ask one question:
What relationship does the word express?
- A past period? Therefore→ at that time, back then
- The next step? → next
- A later event? → afterward, later
- A formal chronological relationship? → subsequently
- Continuation from a particular point? → thereafter
- A condition? → in that case
- A logical consequence? → therefore, consequently
- A casual past reference? → back then
This approach is more reliable than searching for a one-to-one synonym.
Common Collocations With Then
Then frequently appears in familiar expressions and structures:
- back then
- until then
- by then
- just then
- from then on
- then and …there
- sometimes
- now and then
- first…… then…
- if… then…
Each expression has its meaning.
For example:
“I knew him back then.”
means at that earlier time.
But:
“I’ll wait until then.”
means up to that specified time.
And:
“She agreed then and there.”
means immediately, at that exact moment.
Replacing then without understanding the complete expression can change the meaning.
Grammar Tips for Using Then Correctly
Use “then” for sequence
“She opened the door, then walked inside.”
Use “then” after an if-clause when emphasizing a consequence
“If you need help, then ask.”
The then can often be omitted:
“If you need help, ask.”
Use a comma carefully
When then joins two independent clauses, punctuation depends on the sentence structure.
“We finished the meeting, and then we left.”
A comma is commonly used before and then when two complete clauses are joined.
Don’t automatically replace every “then”
Replacing a common word merely to sound sophisticated can make writing less natural.
“We subsequently went home.”
It may be grammatically correct, but:
“We then went home.”
is usually cleaner when the context is simple.
Common Mistakes With Then Synonyms
Mistake 1: Treating every alternative as interchangeable
Afterward, therefore, and at that time describe different relationships.
Mistake 2: Overusing formal vocabulary
Words such as thereafter and subsequently can make ordinary writing unnecessarily stiff.
Mistake 3: Confusing then and than
Then usually relates to time, sequence, or consequence.
Than is generally used in comparisons:
“She is taller than her brother.”
Mistake 4: Changing the meaning while avoiding repetition
If then is accurate, there is no requirement to replace it. Good writing values precision over artificial vocabulary variety.
How to Use Then Synonyms in Professional Writing
Professional writers should prioritize precision, register, and readability.
Instead of repeatedly writing:
“The company completed the review. Then it changed the policy. Then it notified employees.”
you might write:
“The company completed the review, subsequently changed the policy, and notified employees.”
But if the sequence itself is important:
“The company completed the review, then changed the policy and notified employees.”
is perfectly effective.
The best editing decision depends on whether you want to emphasize chronology, causation, formality, or continuity.
Then in Creative and Literary Writing
Creative writing gives them a different role. It can create rhythm and movement:
“He looked toward the door, then stopped.”
Repeated then can also deliberately create a fast sequence:
“She ran upstairs, then opened the window, then shouted for help.”
A literary writer might remove one or more repetitions to improve rhythm, but replacing every instance with subsequently would destroy the natural voice.
Related Words and the Lexical Field
Words surrounding then belong to several related semantic groups.
Time:
now, later, earlier, before, afterward, eventually, previously
Sequence:
first, next, afterward, subsequently, finally
Consequence:
therefore, consequently, thus, so
Conditional reasoning:
if, then, otherwise, in that case
Understanding these relationships helps develop vocabulary more effectively than memorizing isolated synonym lists.
Antonyms and Contrasting Terms for Then
There is no single antonym for then because the word has multiple meanings.
When then means a past time, a contrasting term may be now.
“I lived there then, but I live here now.”
When it indicates sequence, a contrasting idea may be before.
“She arrived before the meeting, then left afterward.”
The correct opposite therefore depends on the sense being used.
Practical Vocabulary Upgrade
If you want stronger vocabulary, don’t simply replace then with the longest or most formal word available.
Use this hierarchy:
Simple → Precise → Formal
- then → afterward → subsequently
- then → at that time → during that period
- then → next → at the next stage
- then → after that → thereafter
- then → in that case → under those circumstances
- then → therefore → consequently
The middle option is often the best choice because it adds precision without making the sentence unnecessarily formal.
FAQs About the Synonym
What is the most common synonym for then?
The most common synonym for “then” depends on its meaning. If it refers to something happening afterward, “next” or “later” may work well. If it refers to a previous time, “at that time” is appropriate. For formal writing, “subsequently” or “thereafter” can sometimes replace “then” naturally.
What is a formal synonym for then?
“Subsequently” is one of the strongest formal alternatives to “then” when describing something that happened afterward. “Thereafter” can also work when referring to a period following a particular event. However, these words are more formal than everyday “then,” so they are especially useful in academic, professional, legal, or carefully edited writing.
What is another word for then in chronological order?
When “then” shows chronological order, useful alternatives include “next,” “afterward,” “subsequently,” “later,” and “thereafter.” The best choice depends on the sentence. “Next” is straightforward and conversational, while “subsequently” sounds more formal. “Afterward” clearly indicates that something happened following an earlier event.
Can next be used as a synonym for then?
Yes, “next” can replace “then” when the word indicates the following event or step in a sequence. For example, “First, mix the ingredients; then add the flour” can become “First, mix the ingredients; next, add the flour.” However, “next” cannot replace every use of “then,” particularly when “then” refers to a past time.
What is a synonym for then in formal writing?
In formal writing, “subsequently,” “thereafter,” “at that time,” and “following this” can sometimes replace “then.” The correct choice depends on the intended meaning. “Subsequently” is useful for describing a later event, whereas “at that time” specifically refers to a particular period in the past.
What is a synonym for then meaning afterward?
When “then” means “afterward,” suitable synonyms include “afterward,” “later,” “subsequently,” and “thereafter.” For example, “She finished her work and then went home” could become “She finished her work and afterward went home.” Among these options, “afterward” is generally natural and easy to understand.
What is a synonym for then meaning at that time?
When “then” refers to a particular time in the past, “at that time” is one of the clearest alternatives. Depending on context, “back then” may work in informal writing, while “during that period” can sound more formal. The important point is to preserve the original time-related meaning.
What word can replace then in an essay?
In an essay, alternatives such as “subsequently,” “thereafter,” “afterward,” “following this,” or “as a result” may work depending on the relationship between ideas. However, replacing every instance of “then” is unnecessary. Sometimes “then” is the clearest and most natural word, especially when the sentence is already easy to follow.
Is thereafter the same as then?
“Thereafter” and “then” can have similar meanings when both describe something happening after a particular event or time. However, “thereafter” is more formal and specifically emphasizes the period following something previously mentioned. Because of its formal tone, it is more common in academic, legal, historical, and professional writing.
How do I choose the best then synonym?
Choose a synonym based on the exact function of “then” in your sentence. Use “next” for sequence, “afterward” or “later” for subsequent time, “subsequently” for formal writing, “at that time” for a specific past period, and “therefore” only when “then” expresses a logical result. Context should always guide the choice.
Conclusion:
Finding the right then synonym depends on what “then” means in a sentence. It can refer to a specific time, show what happened next, describe a result, or introduce the next step in a sequence. Words such as afterward, next, subsequently, later, therefore, and at that time may work, but each carries a slightly different meaning and tone. Therefore, the best alternative should always match the context rather than simply replacing “then” word for word.
In casual conversation, simple choices like next or later often sound natural. In academic or professional writing, subsequently or thereafter may create a more formal tone. By understanding these differences, you can make your writing clearer, smoother, and more precise. Ultimately, choosing a suitable then synonym is less about finding one perfect replacement and more about selecting the word that communicates your intended relationship between ideas.
