You are watching: Is there a comma after thus

Since girlfriend are analysis this short article in English, the odds are you already know what the connect “so” means. You probably also know the “thus”, “therefore”, and “hence” typical basically the exact same as “so”, and you are wondering what the difference is. If this is the case, this post is simply for you.

Before moving on to the details words, it should be detailed that “thus”, “therefore”, and “hence” space all quite formal and much much more common in creating than in daily conversation, whereby they are practically always substituted through “so”.

“Thus” and also “so”

The most essential difference in between “thus” and “so” is that “so” is a conjunction (meaning “and for that reason”, “and due to the fact that of that”), vice versa, “thus” is an adverb (synonymous v “consequently”). Because that example, the sentence

“Thus” is typically separated from the remainder of the sentence by commas, yet the commas are frequently omitted if this would cause three commas in a heat (as in the third example).
