Shirley, this must have been addressed. Would someone kindly advise me where I can find a thorough, conclusive discussion on the subject of the word "Language" -- in particular "human language" vs. "animal language." I know what people are saying -- opinions rather than formal explanations. Or does this wax too 'philosophical'? What is: (the referent for) "language," precisely, in unambiguous, nonjudgmental objective (!) terms that average people will accept?

θank you.
