Truth can be about facts (untouchable) Real is mostly about objects. Blank is a missing thing or space that may need to be filled in. Free is about without........ or without payment- and these missing things are not needed nor wanted

what's the different between"true"and "real""free"and "blank" = CORRECTED: What's the DIFFERENCE between "true" and "real," and "free" and "blank"? "true": can be verified by reality or is a fact "real": has material or expressive form "free": has no monetary cost; unshackled "blank": empty (such as a "blank" face, which is empty of expression, or a "blank" check, which has not been filled out yet)

Real is an attribute describing something that is happening, that exists , in contrast to characters from fairy tales, from a drawing about a flying house, from a creature half horse and half bull and from the little houses of the happy Smurfs. Those things don't exist as things in the world or universe, but only in the imagination, they are not 'real'. True: it is a property about statements, for instance if you say /it is raining/ during a rainy day, the statement is true . / I am writing about the city of Shanghai/ : this is not true, it is false, as I am writing about something else. The statement / the Smurfs are real/ is not true. The statement / the Smurfs are usually happy/ is true, although the Smurfs are not real, it is a statement regarding their behavior in their non-real existence, as their author described them. Note: in case you don't know about the Smurfs, they are a people from a famous cartoon (French origin); they live in a village deep in the forest, they are small, funny and their skin is blue-colored. They also have a couple of enemies.
