If you are looking for a furthermore synonym, the best choice depends on your sentence, tone, and purpose. Moreover, additionally, in addition, also, what’s more, and besides can all introduce extra information, but they are not interchangeable in every context. “Furthermore” is a formal adverb used to add another point, often one that supports or strengthens the preceding idea.
This guide explains the most useful alternatives, their meanings, formality, examples, and the situations where each works best.
What Does “Furthermore” Mean?
Furthermore is an adverb meaning “in addition” or “more importantly.” It introduces another piece of information that supports, extends, or reinforces the previous statement.
Example:
The new library has a larger collection. Furthermore, it offers free study rooms.
The second sentence adds another positive point about the library.
“Furthermore” is generally considered formal, so it is particularly suitable for academic, professional, and other formal writing.
Part of Speech
Furthermore is an adverb, specifically a conjunctive or linking adverb used to connect ideas.
It commonly appears at the beginning of a sentence:
Furthermore, the research supports the original conclusion.
It can also occur within a sentence:
The results, furthermore, were consistent with earlier findings.
Best Furthermore Synonyms
Here are some of the most useful alternatives to furthermore:
| Synonym | Meaning / Use | Tone | Example |
|---|---|---|---|
| Moreover | Adds and often strengthens a point | Formal | Moreover, the plan saves money. |
| Additionally | Adds another fact or idea | Formal/neutral | Additionally, the course includes practical work. |
| In addition | Introduces extra information | Formal/neutral | In addition, students receive online materials. |
| Also | Adds information simply | Neutral | The book is useful and also affordable. |
| What’s more | Adds another notable point | Conversational | What’s more, admission is free. |
| Besides | Adds another consideration | Neutral/informal | Besides, we already have enough evidence. |
| Plus | Adds an extra point casually | Informal | The phone is affordable, plus it has a good camera. |
| As well | Adds something to a statement | Neutral | She speaks French and Spanish as well. |
| Too | Adds information, usually at the end | Informal/neutral | He enjoys science too. |
| On top of that | Adds another point, often emphatically | Informal | The car is expensive, and on top of that, it needs repairs. |
| Further | Introduces another related point | Formal | Further, the findings require additional investigation. |
| What is more | Adds a point with emphasis | Formal/neutral | What is more, the proposal is environmentally friendly. |
| Equally | Introduces an equally important consideration | Formal | Equally, the costs must be considered. |
| Likewise | Shows similarity rather than simple addition | Formal | The first study was successful; likewise, the second produced strong results. |
| Similarly | Adds a comparable idea | Neutral/formal | Similarly, the second group showed improvement. |
| Not to mention | Adds an additional point, often persuasive | Informal | The location is convenient, not to mention inexpensive. |
Not all of these are perfect replacements in every sentence. For example, likewise and similarly normally express similarity, while furthermore simply adds information. Choosing a synonym based on context is therefore more accurate than treating every related transition as interchangeable.
1. Moreover
Moreover is probably the closest formal alternative to furthermore.
It introduces additional information and can suggest that the new point makes the overall argument stronger.
Example:
The proposal would reduce costs. Moreover, it would improve efficiency.
Best for:
- Academic essays
- Research writing
- Formal arguments
- Professional reports
- Formal articles
If you want a direct formal replacement for “furthermore,” moreover is usually one of the safest choices. Cambridge Dictionary also identifies “moreover” as a synonym of “furthermore.”
2. Additionally
Additionally means that something else is being added to the information already given.
Example:
The program provides free training. Additionally, participants receive learning materials.
It works especially well in reports, academic writing, business communication, and explanatory content.
Compared with moreover, “additionally” generally sounds more neutral. It adds information without necessarily suggesting that the new point is more important.
3. In Addition
In addition is another highly versatile alternative.
Example:
The hotel offers free breakfast. In addition, guests can use the fitness center.
It is useful because it clearly signals that another fact is coming.
Unlike some casual alternatives, in addition fits comfortably into formal and professional writing.
“In Addition” vs. “In Addition To”
Be careful with their grammatical patterns.
In addition, can introduce another clause:
In addition, the company offers flexible working hours.
In addition to is followed by a noun or gerund:
In addition to flexible hours, the company offers remote work.
So in addition to is not simply interchangeable with furthermore.
4. Also
Also is much more common and flexible than furthermore.
Example:
The course is affordable. It is also available online.
It works naturally in everyday English, business writing, and general communication.
Because it is less formal, it may sound more natural than “furthermore” in many ordinary sentences.
Compare:
Furthermore, the restaurant offers vegetarian meals.
with:
The restaurant also offers vegetarian meals.
The second version is simpler and more conversational.
5. What’s More
What’s more introduces an additional point, often one that the writer considers particularly interesting or important.
Example:
The apartment is close to the university. What’s more, it has excellent public transportation nearby.
It is more conversational than furthermore and can work well in blogs, articles, personal writing, and informal explanations.
6. Besides
Besides can introduce an additional reason, fact, or consideration.
Example:
We should take the train. Besides, it is cheaper than driving.
However, “besides” can carry a slightly different conversational feeling from “furthermore.” It may sound like the speaker is adding another reason to support a decision.
It is therefore useful when the additional point is part of an argument.
7. Plus
Plus is an informal way to add another positive or relevant point.
Example:
The laptop is lightweight. Plus, its battery lasts all day.
It works naturally in casual speech, messages, blogs, and informal writing.
It would usually be inappropriate in a highly formal academic sentence where moreover, additionally, or in addition would be more suitable.
Formal Synonyms for Furthermore
If you are writing an essay, report, thesis, or professional document, consider these alternatives:
- Moreover
- Additionally
- In addition
- Further
- What is more
- Equally
Example
The study produced reliable results. Moreover, the findings were consistent across multiple tests.
Or:
The study produced reliable results. Additionally, the findings were consistent across multiple tests.
The first emphasizes the additional point somewhat more strongly; the second presents it more neutrally.
Informal Synonyms for Furthermore
For casual communication, these alternatives may sound more natural:
- Also
- Plus
- What’s more
- Besides
- On top of that
- Too
- As well
Example
Formal:
Furthermore, the event provides free transportation.
Informal:
Plus, the event provides free transportation.
The information is similar, but the tone is different.
Furthermore Synonyms for Academic Writing
Academic writing often needs transitions that connect evidence and arguments without sounding conversational.
The strongest choices include:
Moreover
The results support the hypothesis. Moreover, they correspond with previous findings.
Additionally
The experiment produced consistent results. Additionally, the researchers identified several new patterns.
In addition
The method is inexpensive. In addition, it requires relatively little equipment.
Further
Further, the findings indicate a need for additional research.
However, do not replace every instance of “furthermore” automatically. Repeated transition words can make academic prose feel mechanical. Sometimes the clearest option is simply to connect two sentences naturally without a transition.
Furthermore vs. Moreover
These two words are extremely close.
| Feature | Furthermore | Moreover |
|---|---|---|
| Basic function | Adds information | Adds information |
| Tone | Formal | Formal |
| Common use | Academic and professional writing | Academic and persuasive writing |
| Emphasis | Additional supporting point | Often adds a stronger or important point |
| Direct substitute? | Yes, in many contexts | Yes, in many contexts |
Consider:
The proposal is affordable. Furthermore, it is easy to implement.
and:
The proposal is affordable. Moreover, it is easy to implement.
Both are grammatically correct. In many situations, the difference is subtle rather than absolute. “Moreover” can place slightly more rhetorical weight on the following point, but the two words are frequently interchangeable.
Furthermore vs. Additionally
Both words add information, but their tone can differ.
Furthermore often feels more argumentative or emphatic:
The policy is expensive. Furthermore, it could create additional administrative problems.
Additionally tends to sound more neutral:
The policy is expensive. Additionally, it could create administrative problems.
If you are simply adding another fact, additionally is often a smooth choice.
If you are building an argument, furthermore or moreover may sound more purposeful.
Furthermore vs. Also
The biggest difference is usually formality.
Furthermore, the product is environmentally friendly.
sounds formal.
The product is also environmentally friendly.
sounds natural and neutral.
“Also” is often preferable when you want clear, uncomplicated English. “Furthermore” is useful when you deliberately want a formal transition between ideas.
When Not to Use “Furthermore”
“Furthermore” should introduce an additional idea. It should not normally be used to show contrast, cause, sequence, or conclusion.
For example, if two ideas contradict each other, use a contrast transition:
The product is inexpensive. However, it is not very durable.
Using “furthermore” here would give the wrong relationship between the ideas.
Likewise, if you are showing a result, words such as therefore, thus, or as a result may be more appropriate.
Choosing a transition based on the logical relationship between ideas is more important than simply finding a replacement word.
Common Mistakes With Furthermore
1. Using it for contrast
❌ Incorrect relationship:
The product is affordable. Furthermore, it is difficult to maintain.
If the second sentence is intended as a disadvantage or contrast, however may be appropriate instead.
2. Using it repeatedly
A paragraph containing:
Furthermore… Furthermore… Furthermore…
can sound repetitive.
Vary your sentence structure and use alternatives only when they genuinely improve the flow.
3. Using a synonym that changes the meaning
Do not replace “furthermore” with likewise unless you are actually showing similarity.
The first team improved. Likewise, the second team improved.
“Likewise” means something closer to “in the same way,” not simply “in addition.”
4. Making every sentence more formal
A synonym is not automatically better because it sounds sophisticated.
Instead of:
Furthermore, I would like to inform you that…
a simpler sentence may be clearer:
I also want to let you know that…
Good writing chooses the word that best fits the reader and context.
How to Choose the Best Furthermore Synonym
Use this simple guide:
- Formal academic argument: Moreover
- Neutral academic addition: Additionally
- Clear formal addition: In addition
- Everyday English: Also
- Conversational emphasis: What’s more
- Adding another reason: Besides
- Very casual writing: Plus
- Adding something at the end: Too / as well
- Showing similarity: Likewise / similarly
- Emphasizing another important point: Moreover / what is more
The best synonym is therefore not always the most formal one. It is the one that expresses the intended relationship between your ideas while matching the tone of your writing.
