What punctuation does you use for therefore?

"Therefore" is usually followed by a comma, especially when it introduces a new clause or phrase.

Here's an example:

However, if "therefore" is used at the beginning of a sentence, it may be followed by a colon instead of a comma:

* Therefore, we decided to go for a walk.

Ultimately, the best punctuation for "therefore" depends on the specific context of the sentence.
