Therefore or therefor which one belongs in your sentence? They differ by only one letter, but their meanings are completely different. Therefore means “for that reason” or “as a result,” while therefor means “for that” or “for it.” In everyday writing, therefore is almost always the word you need.
Quick Answer:
Use therefore to show a result or conclusion: The road was closed; therefore, we turned back. Use therefor when you mean “for that” or “for it.” Because that meaning is uncommon, therefor appears mainly in legal and highly formal writing.
Therefore vs. Therefor
| Word | Meaning | Common Use |
| therefore | For that reason; as a result | Everyday, academic, and formal writing |
| therefor | For that; for it | Mainly legal or formal writing |
When to Use Therefore
Therefore shows that one thing follows from another. It is similar to thus, hence, consequently, and as a result.
The evidence was incomplete; therefore, the case was delayed.
Therefore can appear at the beginning, middle, or end of a sentence.
Punctuation With Therefore
When therefore connects two complete clauses, use a semicolon before it and a comma after it:
The weather was getting worse; therefore, we canceled the trip.
When it interrupts a sentence, commas can set it apart:
The trip was, therefore, canceled.
It can also introduce a sentence:
Therefore, we decided to wait.
When to Use Therefor
Therefor is a real word, but it is uncommon. It means “for that” or “for it” and is mainly found in legal, contractual, or older formal writing.
The tenant received compensation therefor.
In normal conversation and general writing, you are unlikely to need therefor.
Common Mistake
Do not use therefor as a shorter form of therefore. If you mean “as a result” or “for that reason,” use therefore.
A useful test is simple: if as a result, thus, or hence fits, choose therefore.
Pronunciation
- Therefore: /ˈðer.fɔːr/
- Therefor: /ðerˈfɔːr/
They can sound similar, which makes the spelling easy to confuse.
Examples
- The store was closed; therefore, we went home.
- She had prepared well and therefore felt confident.
- The roads were flooded; therefore, the match was postponed.
- The buyer received compensation therefor.
- The contract provides payment therefor under certain conditions.
- The deadline had passed; therefore, the application was rejected.
Memory Trick
Therefore = for that reason.
If you can replace it with “as a result,” use therefore.
Therefor = for that.
Think of it as the rare formal or legal word.
