Openest → It is formed from "open" (from Old English "open", meaning not closed or obstructed) and the superlative suffix "-est" (meaning most). The word "openest" means the most open or having the least obstruction.
Think of the word 'open' meaning not closed, and when you add '-est', it indicates the highest degree. So, 'openest' means the most open.
