The Importance of Naturalism in Conlangs

I love that idea so it's you just you just slap the noun class on the onto the verb stem and voila you have an infinitive yay I think this is one of the things a lot of conlangs lag is that or at least when you start you want to make a section for everything. Some modern ones still do this some words switch gender in the plural that's interesting. How does that work typically this is not happening to people okay zapping to words like tree.
