Therefore vs. Therefor – Which is Correct?
When comparing “therefore” and “therefor,” the correct and commonly used word in modern English is therefore. “Therefore” is an adverb meaning “for that reason” or “consequently.” While “therefor” exists, it is an archaic or highly specialized legal term meaning “for it” or “for that,” and is often encountered as a misspelling of “therefore.”
Therefore or Therefor – Which is Correct?
The distinction between “therefore” and “therefor” is straightforward in contemporary usage. Therefore is the standard adverb used to indicate a consequence, result, or conclusion. It acts as a conjunctive adverb, connecting two independent clauses or sentences, showing a cause-and-effect relationship.
Therefor, on the other hand, is largely obsolete in general English and is primarily found in legal or very formal, archaic contexts. It means “for it” or “for that,” referring back to a previously mentioned item or concept. Its infrequent use often leads to it being mistaken for a misspelling of “therefore.” For all practical purposes in everyday writing and most professional contexts, “therefore” is the correct choice.
The Best Trick to Remember the Difference
The easiest trick to remember the difference is to think about the “reason.” If you mean “for that reason,” you need the word with “re” in the middle: therefore.
Alternatively, consider replacing the word with synonyms. If you can replace it with “consequently,” “as a result,” or “thus,” then “therefore” is correct. If you are trying to say “for it” or “for that specific thing,” you likely need to rephrase your sentence or are encountering the rare, archaic “therefor.”
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| Therefore | Conjunctive Adverb | For that reason; consequently; as a result. | She studied diligently; therefore, she passed the exam. |
| Therefor | Archaic Adverb | For it; for that (rare, mostly legal). | The contract specifies a fee, and payment therefor is due immediately. |
How to Use Therefore
“Therefore” is a versatile conjunctive adverb that introduces a logical consequence or conclusion. It can connect two independent clauses, often preceded by a semicolon and followed by a comma, or it can begin a new sentence. It adds a formal and logical tone to writing, indicating that what follows is a direct result of what was previously stated.
Example 1: The experiment yielded unexpected results; therefore, further investigation is required.
Example 2: The deadline is approaching rapidly. Therefore, we must accelerate our efforts to complete the project on time.
Example 3: He was late for the meeting, and therefore, he missed the crucial opening remarks.
Etymology of the word Therefore
The word “therefore” originated in Middle English, combining “there” (meaning “in that place” or “at that point”) and “for” (meaning “because of” or “on account of”). Its usage as “for that reason” or “consequently” has been consistent since the 14th century, evolving from a literal sense of “for that” to its modern function as an indicator of logical deduction.
Related Concepts
Understanding broader grammatical concepts can help solidify the correct use of “therefore” and avoid confusion with “therefor.”
- Conjunctive Adverbs: These words (like therefore, however, moreover, consequently) connect two independent clauses, showing a relationship between them. They are typically preceded by a semicolon and followed by a comma when connecting clauses (e.g., “She studied; therefore, she succeeded.”).
- Adverbs: Adverbs modify verbs, adjectives, or other adverbs, providing information about how, when, where, or to what extent an action occurs. “Therefore” functions as an adverb that modifies the entire clause it introduces, indicating a logical relationship.
Examples from Media and Literature
- “I think, therefore I am.” – René Descartes (famous philosophical statement, translated from Latin)
- “All men are mortal; Socrates is a man; therefore, Socrates is mortal.” – Classic syllogism demonstrating logical deduction.
- “The witness provided conflicting testimonies; therefore, her credibility was questioned by the jury.” – News report analysis
- “She had always dreamed of traveling the world, and therefore, saved every penny she earned.” – Fictional narrative

Frequently Asked Questions
Question 1: Can “therefore” start a sentence?
Yes, “therefore” can absolutely start a sentence. When it does, it typically refers back to the preceding sentence or idea and should be followed by a comma (e.g., “The weather improved. Therefore, we decided to go for a hike.”).
Question 2: Is “therefor” ever correct in modern English?
“Therefor” is rarely correct in general modern English. Its primary use is in highly specialized legal or formal contexts, where it means “for it” or “for that.” In everyday writing, it is almost always a misspelling of “therefore.”
Question 3: How does “therefore” differ from “so”?
Both “therefore” and “so” indicate a consequence, but “therefore” is generally more formal and emphasizes a logical deduction. “So” is more casual and can also indicate purpose (“I studied so I could pass”) or simply a result (“It rained, so we stayed inside”). “Therefore” specifically implies “for that reason.”
Conclusion
In the “therefore vs therefor” debate, therefore is the undisputed champion for expressing consequence and logical deduction in modern English. While “therefor” has a niche existence in archaic or legal language, its use is so specialized that it is almost always an error when encountered in general writing. By remembering that “therefore” means “for that reason,” you can confidently apply it to connect ideas and build strong, logical arguments.
Pro Tip: Always proofread carefully. Misusing “therefore” for “therefor” can subtly undermine your professional credibility, suggesting a lack of attention to detail in your writing.
