Infernally means something is done in a manner related to hell or the underworld—think intensely unpleasant or diabolical. It's used to describe actions, situations, or conditions that are extremely irritating or difficult. The term carries a strong negative connotation, implying torment or evil. In contrast to something heavenly, it leans towards the torturous. Imagine the heat in the desert intensified a thousandfold; that's infernally hot. It's the opposite of something delightful or divine.
