Can words mean anything at all?
Imagine you're at a party and someone says, "The sky is purple." You know the sky is usually blue, so you wonder if they're joking or mistaken.
The idea is that some statements can't be proven true or false through experience or logic alone, like saying "The sky is purple."
Example
The statement "The sky is purple" doesn't fit the usual criteria for meaning because it's not something you can verify through observation or logical analysis.
Remember this
Quine's challenge to verificationism is that not all meaningful statements can be empirically verified or logically defined.
