When a brand new teacher makes an amateurish try at getting his class's attention, he doesn't exactly sound like an authority figure. At the heart of amateurish is the noun amateur, or "beginner." The oldest meaning of amateur is "lover of something," from the Latin amatorem, "lover," although by the late 1700's it came to mean "dabbler," or not a professional.
