Choosing between “therefor” and “therefore” can be confusing because the two words look almost identical. Yet, they do not have the same meaning or use.
If you have ever stopped while writing an email, essay, report, or social media post and wondered whether therefor or therefore is correct, you are not alone. The extra e changes more than the spelling—it changes the word’s function.
The good news is simple: therefore is the word you will normally need. It means “for that reason,” “as a result,” or “consequently.” For example, “It was raining; therefore, we stayed home.”
Therefor is a much less common word. It is mainly found in legal and formal writing, where it means “for that” or “in return for that.”
This guide explains the difference between therefor or therefore, their history, common mistakes, British and American usage, and real-life examples. By the end, you will know exactly which spelling to choose.
Therefor or Therefore – Quick Answer
The correct word for most everyday writing is therefore.
Therefore means for that reason, because of that, or as a result.
The store was closed; therefore, we went home.
She studied hard. Therefore, she passed the exam.
Therefor is a different word. It means “for that” and is rarely used outside legal or very formal language.
The company received payment therefor.
In modern everyday English, you will almost always want therefore, not therefor.
Quick comparison
| Word | Meaning | Common use |
|---|---|---|
| Therefore | For that reason; as a result | Everyday and formal English |
| Therefor | For that; in return for that | Mainly legal/formal writing |
Easy memory trick
Think:
There + fore = therefore = for that reason
If you are saying “as a result,” use therefore.
The Origin of Therefor and Therefore
Both therefor and therefore come from older forms of English built around the word there.
The word therefore combines there with fore, an old word related to “before” or “in front.” Over time, therefore developed the meaning “for that reason” or “because of that.”
For example:
He was tired; therefore, he went to bed.
The word therefor has a different historical function. It combines there with for and originally meant something close to “for that.”
It still appears in some legal language:
Payment was made therefor.
This means payment was made for that thing or service.
The two words became easy to confuse because they look almost the same. The difference is only one letter, but the meanings are distinct.
Why does “therefor” look incomplete?
Modern readers may expect therefor to be a shortened version of therefore. It is not simply a spelling mistake, though.
Therefor is a real English word. It has its own meaning and grammatical use.
The problem is that it is uncommon in modern everyday English. That makes it easy to mistake for a typo.
British English vs American English Spelling
There is no major British-versus-American spelling difference between these two words.
Both British English and American English use:
- therefore for “as a result”
- therefor mainly in specialized legal or formal contexts
So you should not choose therefor simply because you are writing for a British audience or therefore because you are writing for an American audience.
Comparison table
| Feature | British English | American English |
|---|---|---|
| Correct common form | Therefore | Therefore |
| Meaning | For that reason | For that reason |
| Legal word | Therefor | Therefor |
| Common everyday use | Therefore | Therefore |
| Spelling difference | None | None |
Examples
British English:
The train was delayed; therefore, I arrived late.
American English:
The train was delayed; therefore, I arrived late.
The spelling stays the same.
The important difference is meaning, not regional spelling.
Which Spelling Should You Use?
For almost all general writing, choose therefore.
If you write everyday English
Use therefore when you mean:
- as a result
- consequently
- for that reason
- because of that
Example:
The weather was bad; therefore, the game was canceled.
If you write academic papers
Therefore is common in academic writing because it helps show a logical result.
The sample size was small; therefore, the results should be interpreted carefully.
If you write business emails
Use therefore when explaining a conclusion or action.
The deadline has changed. Therefore, we need to update the schedule.
If you write legal documents
You may encounter therefor, but do not replace therefore with it.
Therefor is appropriate only when its specific meaning fits the sentence.
For global English
If your readers come from different countries, therefore is the safest choice when you mean “as a result.”
It is widely understood and commonly used.
Common Mistakes with Therefor or Therefore
The most common mistake is using therefor when you mean therefore.
Mistake 1: Using “therefor” to mean “as a result”
❌ The road was closed; therefor, we took another route.
✅ The road was closed; therefore, we took another route.
The second sentence is correct because the writer means “as a result.”
Mistake 2: Thinking “therefor” is a shorter spelling
❌ Therefor is simply a shortened form of therefore.
✅ Therefor is a separate word with a different meaning.
Mistake 3: Adding an extra word
Sometimes writers use phrases such as:
The project was late, and therefore because of this, the team apologized.
This is unnecessarily complicated.
Better:
The project was late; therefore, the team apologized.
Mistake 4: Using “therefore” when “therefor” is required
This is less common, but it can happen in legal writing.
If a sentence means “for that,” then therefor may be correct.
The buyer paid the agreed amount therefor.
Here, therefor does not mean “as a result.”
Therefor or Therefore – Side-by-Side Comparison
| Variation | Correct? | Meaning | Example |
|---|---|---|---|
| Therefore | ✅ | As a result | It rained; therefore, we stayed inside. |
| Therefor | ✅ | For that | Payment was made therefor. |
| There fore | ❌ | Not standard | Avoid this form. |
| Therefore in place of therefor | ❌ | Wrong meaning in legal context | Check the intended meaning. |
| Therefor in place of therefore | ❌ | Wrong meaning in normal writing | Use therefore. |
The key is to remember that both spellings can be correct, but they are not interchangeable.
Therefor or Therefore in Everyday Examples
1. In emails
Correct:
