Fondest → It is formed from "fond" (from Old French *fondre*, meaning to melt or to be tender) and the suffix "-est" (indicating the superlative degree). The word "fondest" means having the greatest affection or tenderness.
Think of someone who is 'tender' ('fond') and has the 'greatest' ('-est') affection for something — that's why fondest means having the most affection.
