Barest → It is formed from "bare" (from Old English "bær", meaning uncovered or exposed) and the superlative suffix "-est" (meaning most). The word "barest" means the most uncovered or exposed, indicating the least amount of covering or adornment.
Think of 'bare' meaning uncovered, and when you add '-est', it indicates the most uncovered. So, 'barest' means the most exposed.
