Morphology

permanganic + acid

The compound is compositionally regular: 'permanganic' (relating to permanganate/manganese oxidation states) simply modifies 'acid', so the phrase denotes the acid related to permanganate. This follows standard chemical naming patterns familiar across languages, so a learner who knows both constituents can infer the meaning.

Etymology

Permanganic acid is named from its parts: 'per-' meaning 'extra oxygen', 'manganic' from the metal manganese, and 'acid' meaning 'a sour chemical'. That's why the name points to a deep purple, oxygen-rich acid seen only in solution and used to make permanganate salts.
