After scrolling through the 12 common errors link, I feel like I have a really hard time with commas. I never know when is the right time to use them and when not to. Ive always been told to make sure you don’t use too many commas because it can make the sentence choppy and hard to read. Commas are by far my biggest enemy, but I also sometimes have trouble with making my pronouns clear. Sometimes my pronouns make literally zero sense to be where they are, but hey, we’re learning and I plan to learn a lot this year to fix the mistakes I make when writing.
