In English a noun form of the doer of a verb is usually formed by '-er' sound, e.g. run - runner, teach - teacher, sell - seller. Then the noun form of the action of the verb is usually the '-ing' form, e.g. teach - teaching, run - running, sell - selling. Is there a comparative way to construct noun from of French verbs?
P.S. I'm not a native speaker of English or French.
