People might want to look up "inversion" as well;
There's one guy who refused to look up the word 'metaphysics" for years even after I defined it FOR HIM. Maybe I should use the word "epistemology" but this isn't the right word and is harder to deduce its meaning from context. Most of the time I use the word the word "metaphysics" you could figure out what it means by how it's used in a sentence if you merely assume the sentence makes sense. "Science has no meaning outside its metaphysics" is a tautology that defines the word. But people now days don't understand metaphysics so the solution to the sentence is a null set for most individuals who then can't be bothered to use a dictionary.
The irony is I had to use a dictionary more times to solve Mercer's PT than Allen likely used it to generate his translation.
Reality isn't rocket science but everyone doesn't really know everything.
