A wave is a distinction between higher density vs. lower, or higher field-amplitude or not. Waves could not exist without such a distinction. In physics everything (?) is made of waves. But similarly in semantics words can only have meaning by describing both what they refer to and what they don't refer to by a given word or sentence. So, "meaning" is a sort of wave I guess.
