Sorry it took a while I’m not usually on wattpad a lot. Here are the tips for English grammar lol.
Using pronouns are very important in English since our words don’t have assigned genders like Spanish. So, for masculine characters you would use “he” or “him” when referring to them. When referring to feminine characters you want to use “she” or “her”.
Quotation marks are not just for quoting what someone has said, they also show that someone in the story is speaking.
-For example… “I need to talk to you”, Shuri said.
After the end of a sentence (followed by the correct punctuation like a period), the next sentence always starts with a capital letter.
I really hope this helps and I won’t mind if you want to learn more ^3^.
