Therefor or Therefore | Spelling, Difference & Definition

Therefore and therefor (spelled without an “e”) are two different words.

  • Therefore is a commonly used adverb meaning “consequently.”
  • The word therefor is rarely used in modern English, except in legal contexts. It means “for that,” or “in exchange for that.”
Therefore vs therefor examples
Therefore in a sentence Therefor in a sentence
She spent a few years in France and therefore speaks good French. The Investigator shall assess the damages and determine the persons liable therefor.
Therefore, the decision was made to postpone the event. The Landlord shall provide the keys and reserves the right to charge a security deposit therefor.

Therefor meaning

Nowadays, the adverb therefor is only really used in legal English. If you use it in other contexts, it has a very old-fashioned, formal effect.

“Therefor” means “for that,” “as a result of that,” or “in exchange for that,” and is not normally used at the beginning of a sentence or clause. It is pronounced with the stress on the second syllable [therefor].

Therefor in a sentence examples
The Client shall be notified of faults and reimbursed for damages therefor. [“Therefor” means “as a result of the faults”]

The Vendor shall deliver the ordered software products and will invoice the Client for the license fees therefor. [“Therefor” means “for the software products”]

Therefore meaning

Therefore means “consequently” or “as a result.” It is a conjunctive adverb that links two ideas or sentences. You pronounce it with the stress on the first syllable [therefore].

Therefore in a sentence examples
The bicycle was damaged and therefore sent for repair.

Additional time is required. Therefore, the decision will be delayed until next month.

Therefore punctuation

Put a comma after “therefore” if you use it in the following ways.

  • At the beginning of a sentence
  • At the beginning an independent clause immediately after a semicolon.

You don’t need to use a comma before “therefore” if it is part of a compound predicate with two verbs (i.e., the two verbs are “sharing” the same subject).

Commas with therefore examples in a sentence
  • Therefore, the delivery will be delayed. [Beginning of sentence]
  • Therefore the delivery will be delayed.
  • The item is not in stock; therefore, the delivery will be delayed. [Beginning of independent clause after a semicolon]
  • The item is not in stock; therefore the delivery will be delayed.
  • The item was damaged and therefore could not be shipped. [The main verbs “damage” and “ship” are sharing the same subject (“item”)]
  • The item was damaged, and therefore could not be shipped.

Putting commas before and after “therefore” midsentence emphasizes the information that comes before it. So only do it if this is your intention; otherwise, it will unnecessarily break the flow of the sentence.

Commas before and after therefore examples
The next delivery, therefore, will be delayed. [Emphasizes “next delivery” (e.g., to communicate that not all deliveries will be delayed)]

The main office, therefore, will be closed on Mondays. [Emphasizes “main office” (e.g., to communicate that other parts of the building are open)]

Note
When “therefore” is used at the beginning of a sentence or independent clause in British English, it is not generally followed by a comma (e.g., “Therefore the delivery will be delayed”).
