What is the origin of the word cynical?

The Word "cynical" originates from the Greek Word "kynikos," which means "dog-like." This term was associated with the Cynics, a philosophical school in ancient Greece that advocated for a life lived in accordance with nature and rejected societal conventions. The term evolved to describe a distrustful attitude toward the motives of others, reflecting the Cynics' belief that people are motivated solely by self-interest. Over time, "cynical" came to signify a general skepticism about human sincerity and integrity.
