The term 'kind of monk or monkey' can be answered with the 8-letter word 'CAPUCHIN'. Capuchins are a group of New World monkeys that are found in Central and South America. They are characterized by their long, prehensile tails and their brownish-gray fur. They are omnivorous, meaning they eat both plants and animals, and live in large groups. They are also known for their intelligence and use of tools.
