Morphology
perchloric = chloric (semi-transparent) = per + chlor + ic
The adjective is formed by adding the chemical prefix 'per-' to 'chloric'; the composition is visible but the specific chemical sense of 'per-' is specialized and may not be clear to general learners.
Etymology
Perchloric comes from the prefix per- meaning 'very' and chloric from chlorine, a word that originally meant 'green', so perchloric names a very strong chlorine-related acid and its compounds.
