Appreciation is the feeling or expression of gratitude or admiration for something, or the increase in value of something over time.
From the verb "appreciate," rooted in Latin "appretiare" (to value or price). It kept both the emotional sense of valuing and the economic sense of rising worth.
When a house shows appreciation in value and a friend shows appreciation for you, the same mental math is at work: noticing and acknowledging worth. The word quietly bridges money, art, and relationships.
