If I invented a language, there wouldn't be a relationship between plural/singular subject and verbs. This plagues my existence on a daily basis, when I have to prepare and review forms being used for single or multiple inventors. It's so stupid.
If I prepare a series of forms for a single inventor, and then an inventor gets added, I have to back through and change everything from "Applicant requests...." to "Applicants request...." and so on. Verbs should not change based on how many people are doing them.
