Answers to the joining commas quiz

1 Correct. A little tip is that you can use the mnemonic FANBOYS: for, and, nor, but, or, yet and so to help you remember the coordinating conjunctions. In addition lots of people will also treat then as a coordinating conjunction if it’s used instead of and then.

2. Correct. If you normally write in British English, you’re probably happy to leave the joining comma out, whereas it would be more natural to use one in US English. Learn more punctuation differences between UK and US English.

3 Incorrect. If you use a joining comma before a conjunction, the conjunction must be joining two complete grammatical sentences.
