one of the biggest pains in the ass during the school year is teaching the kids the difference between lies, oxymora, ironic statements, and paradoxes.
here's what i generally define each one as:
lie: a statement that is incorrect with the intent of misleading to believe that the lie is truth; being wrong is not a lie, it is a mistake
oxymoron: a statement that essentially has two things being used as one subject despite being opposites
irony: a statement that can be incorrect or inaccurate but with the intention of humor or insult, similar to sarcasm but not quite
paradox: a statement that loops with impossibilities (the do-until loop of language, as i like to say) by contradicting itself
