[Phys-L] superposition and interference



When discussing waves in introductory university physics is there an important distinction to be made between the terms "superposition" and "interference?"

It seems to me that superposition is a principle concept and interference is a descriptor of the phenomenon when superposition happens, but there's not a big reason to draw any kind of "line" between the two. Waves superpose; waves interfere.

Maybe superposition is the more general of the two terms and is something which is always happening. Would one reserve "interference" to a pseudo-steady-state behavior that we see in double-slits, diffraction gratings, and standing waves?
