Under the Lens: Difference between Diabolic and Diabolical
The adjectives diabolic and diabolical are used interchangeably. But if you need to get technical about it you can say that diabolic is having the qualities of a devil while diabolical is appropriate for a devil, in terms of cruelty etc. Hence you might say that diabolic has more direct relation to the devil.
