Dearest is formed from "dear" (from Old English "deore", meaning beloved or precious) and the suffix "-est" (indicating the superlative form). The word "dearest" means the most beloved or precious person or thing.
Think of someone who is the 'most beloved' — 'dear' means beloved, and '-est' shows that they are the highest in that regard.
