Well, maybe – but definitely an unexpected etymology:
Cynic: 1580, from the greek cynikos for dog-like or churlish.
The first Cynics were ancient members of the Cynical philosophical sect, who were widely regarded as being dog-like and churlish because they lived on the street and ignored the rules of decorum.
By the late 17th century, the meaning had morphed into one who is “critical, disparaging the motives of others, captious, sneering, peevish.”
By today’s definition, cynicism is a characteristic rarely found among dogs!!
