Word Choice – Although Versus Though
Irfan’s question: “Please help me understand the use of ‘though’ and ‘although’ and when to add a comma with these words. Here are two examples: 2) Although(,) I have finished your assignment, it was not difficult. 2) I have finished your assignment. It was not difficult though.”
BizWritingTip response: “Although” and “though” when used as conjunctions are interchangeable. (Conjunctions are words that join two separate thoughts.) Although is generally considered more formal than though. (If you wanted to be emphatic, you could also say “even though.”)
The words indicate a condition with an unexpected outcome. One way to ensure you are using the words correctly is to try to replace them with the phrase “despite the fact that.”
Therefore, neither of these words works with your first example. It would be odd to say “Despite the fact that I finished your assignment, it was not difficult.” You would expect to be able to finish an assignment that was not difficult.
Despite the fact that I finished your assignment, it was difficult. (wordy but correct)
Although I finished your assignment, it was difficult. (formal)
Though I finished your assignment, it was not easy. (informal)
Note: The comma is inserted only after the “although” or “though” phrase. It is never placed directly after the word.
Though can also be used an adverb meaning however. (In this usage, though is not interchangeable with although.) Do not insert any commas with the word.
I finished your assignment. It was not difficult however.
I finished your assignment. It was not difficult though.
There is nothing wrong in using “though” as an adverb. Personally, I would have omitted the word as I believe it is not necessary: I finished your assignment. It was not difficult.
