Clearest → It is formed from "clear" (from Old English *cleare*, meaning free from darkness or cloudiness) and the superlative suffix "-est" (meaning most). The word "clearest" means the most free from darkness or cloudiness, indicating the highest degree of clarity.
Think of something that is the "most clear" — the root "clear" means free from darkness, and adding "-est" shows it is the highest level of clarity.
