It’s hard to define ‘real’; it’s not clear that it’s doing any work.
“Hard to define” and “not clearly doing any work” are distinct properties; I’d agree about the former and not the latter. I do find it difficult to give a definition of “real” that isn’t going to break when dealing with unusual border cases; but nevertheless, if I consider the question “Is Harry Potter real?”, or “Is Barack Obama real?”, or “Are atoms real?”, then the two possible answers I could give for each will imply distinct models of reality that anticipate different experiences, and furthermore the word “real” can transfer such a model into someone else’s mind pretty successfully. It doesn’t particularly seem to have any of the characteristics of a non-descriptive term.
