FYI, the no “s” after run is correct. However, the grammar was still wrong because there needs to be a hyphen between “run” and “on.” So it would be “…but run-on sentences.” “Run-on” is technically an adjective describing sentences, and since you can’t really pluralize adjectives, you would not add an “s” to the end of runs. You also missed that he misspelled “doesn’t.” He wrote “dosen’t” instead. But good job correcting, other than those two errors. I support you and correcting people’s grammar 100%. If you have any grammar questions, I will do my best to help.
Ok I’ma shut up now. Bye. 🚶🏻♀️
