I am unsure if the word “therefore” is called a linking adverb.
I have the following sentences. Which version is grammatically acceptable?
My preference, therefore, is to travel by train
My preference is, therefore, to travel by train.
Should “therefore” be separated by a comma?
(I want to use “therefore” in the middle of the sentence. I know it can be used in the beginning and end of a sentence.)
Both sentences are technically grammatically correct. The first sentence using “therefore” before the copula flows better because the verb phrase remains more intact.
