I do not use a comma before and after that word, therefore you will not see it in any sentence I have written.
Yes, a comma is typically placed after "therefore" when it is used to introduce a clause or to clarify the sentence structure. For example, in the sentence "She was late; therefore, we missed the beginning of the movie," the comma after "therefore" helps to separate it from the following clause. However, if "therefore" is used at the end of a sentence, a comma is not necessary.
No, a comma is not typically used after "therefore" unless it is being used to introduce a parenthetical phrase or to provide clarity in the sentence.
Yes. Therefore is usually used at the start of a sentence, to indicate a concluding idea or thought. The comma following it is used as a pause, separating the connecting word from the idea or thought. Strangely enough, a comma is not used in my sentence above because " Therefore " is used as the subject of the verb is, rather than used as a connecting word to a previous idea or statement.
Either a comma or a semi colon can be used, depending on the rest of the sentence.
Yes, usually.
No. Example: "It can therefore be declared that ancestors of modern alligators were present during the time of the dinosaurs."
comma in front of therefore; semi colon in back of therefore
yes
Say your sentence aloud. If you find you pause before the word 'therefore', you will probably want to insert a comma. If you do not pause, no comma is required. Use a comma when the sense requires it, not because you have a specific word in your sentence.
You would put the comma before the therefore. for example: I am a girl, therefore I wear make-up and have long hair. (Just an example not all girls wear make-up and have long hair.)
The phrase "and therefore" typically doesn't require a comma when it connects two clauses. However, if "and therefore" appears at the beginning of a sentence or after a pause for emphasis, a comma may be used before it. For example: "She was tired, and therefore, she went to bed early." In general usage, it's more common to see it without a comma: "She was tired and therefore went to bed early."
