I’m doing some conlanging for a book and I’m having trouble finding the word for how we can take a verb, add -er at the end, and get a word for a person who does that thing. For example, a driver is someone who drives, a commander is someone who commands, a lawyer is someone who laws, and a finger is someone who fings. I am having trouble finding out how other languages noun their verbs in this way since I don’t know what this thing is called. Pls halp.
