The word "丰厚" is formed through the common Chinese morphological process of compounding, where two independent, semantically related characters are combined to create a new, nuanced meaning. The first character, 丰 (fēng), carries the core idea of "abundance" or "plentifulness", while the second, 厚 (hòu), means "thick", "deep", or "substantial". When joined, they create a synergistic adjective that describes something not merely as abundant in quantity but also as rich, generous, and of substantial quality, most frequently applied to abstract nouns like rewards, benefits, gifts, or profits.
