"Cran-" is the eponymous and archetypal "cranberry morpheme", which Wikipedia describes as "a type of bound morpheme that cannot be assigned an independent meaning or grammatical function, but nonetheless serves to distinguish one word from the other." This is roughly what I've always taken a "cranberry morpheme" to be.
But is it itself still one? When I start explaining the cran morpheme to people, I realize that what jumps to mind is that there are other words with "cran": Ocean Spray's well-known Cran-Apple Juice and less-well-known Cran-Strawberry, plenty of "Cran-Orange" recipes on the internet, and the cocktail crantini.
So it now seems that "cran-" has an "independent meaning", which is "pertaining to or containing cranberry". Can it still be a cranberry morpheme? Am I missing something about what a cranberry morpheme is?
