A serial comma (or Oxford comma) is an optional comma used before the last item in a list. For example, “bread, butter, and tax evasion” uses a serial comma, whereas “bread, butter and tax evasion” does not.
Do you use it? Why or not? I myself always use it, and I find it really weird when it’s not there. I don’t perceive any less of a pause between the last two items in a list than between any others, so it feels natural to put a comma there as well. Tbh, I’m so used to it that I usually have to do a double-take when it’s not there (since it looks like a grammar error to me at first).
I’m not a native speaker, but I do prefer using it yeah. In my opinion it reads nicer and less ambiguous. In your example the “butter and tax evasion” otherwise kinda reads like it’s one thing. You need to finish reading the following words before you can be sure that it’s the “terminal and” and not some in-between “and”. But “, and” directly communicates that it’s the terminating “and”, making reading easier.
