Let me remind you.You don't get when you do that as doing philosophy. And it has nothing to do with real as such. It applies to a lot of words like evidence, truth, proof, rational, and so on.
I start with three assumptions. They're assumptions because in each case I can't demonstrate their correctness without first assuming they're correct.
That a world exists external to me.
That my senses are capable of informing me about that world.
That reason is a valid tool.
And I also remind you that you share those assumptions, as you demonstrate by posting on RF, and forming reasoned arguments.
I also note that outside of this sentence there are no absolute truths. But there are still truths.
The self is thus the perceiver of the world external to the self via the senses.
I define objective reality as the world external to the self.
Thus something is real if it exists in reality.
The alternative to existing in reality is to exist solely as a concept or thing imagined in an individual brain. A thing existing only in that manner does not exist in (objective) reality.
Truth is a quality of statements. A statement is true to the extent that it accurately reflects / corresponds with reality.
A fact is an accurate statement about an aspect of reality.
And so on.
