Morphology

permanganate = manganate (opaque) = per + mangan + ate

The addition of 'per-' is a technical chemical marker (indicating a particular oxidation state/extra oxygen) that is not predictable to general learners from the base 'manganate'.

Etymology

Permanganate is built from three parts: per- ('very' or 'thorough'), manganese (the metal name), and the chemical ending -ate (for oxygen-rich salts). So permanganate means a strong, oxygen-rich manganese compound, which fits the dark purple chemical often used as a disinfectant.
