therefore since

USAGE SUMMARY

The phrase "therefore since" is not correct and usable in written English as it combines two conjunctions that serve similar purposes, creating redundancy.
It is generally better to use either "therefore" or "since" separately to convey a cause-and-effect relationship or to indicate a reason. Example: "Since it was raining, we decided to stay indoors." or "We decided to stay indoors; therefore, we missed the event."

Expert writing Tips

Best practice

Choose either "therefore" or "since" depending on whether you want to emphasize the conclusion or the reason. Using both is redundant and grammatically awkward. For example, prefer "Therefore, we stayed home" or "Since it was raining, we stayed home".

Common error

Don't use both "therefore" and "since" together. This creates redundancy because both words serve a similar function in linking cause and effect. Select the word that best fits the flow of your sentence and omit the other.

Linguistic Context

The phrase "therefore since" attempts to function as a conjunction, aiming to connect a cause and its effect or conclusion. However, according to Ludwig AI, this combination is grammatically incorrect due to redundancy, as both words serve similar linking purposes. Examples in Ludwig show the contexts where the phrase occurs, though it should be avoided.

Ludwig's WRAP-UP

In summary, while the expression "therefore since" appears in a number of sources, Ludwig AI indicates that it's considered grammatically incorrect due to its redundant nature. Both words attempt to connect a cause and effect, making their combined use unnecessary. To maintain clarity and grammatical correctness, choose either "therefore" or "since", depending on whether you wish to emphasize the result or the reason. Alternative phrases such as "consequently" or "because" might also serve depending on the intended emphasis and context.
