Use “thus” in a sentence to show the manner or way in which something is done. Use it to describe the extent or degree to which something has taken place. Use the word to show that one event is the result or consequence of a previous event.

“Thus” is an adverb that follows comma rules relating to its adverbial usage. You should place a comma before “thus” when it’s a conjunctive adverb (i.e. “he did this, thus won the game”). You should place a comma after “thus” when it’s an introductory adverb (i.e. “Thus, I was right”).
