Answer: Tiger.
Some extra relevant information:
Tigris, the name of a famous river in the Middle East, is actually derived from the Ancient Greek word “tigris.” However, it is important to note that “tigris” in Ancient Greek does not refer to an animal, as the river was named before the discovery of the animal we now know as the tiger. The term “tigris” was originally used by the Greeks to describe the river itself and was not associated with a specific animal. The name “tigris” eventually became associated with the tiger, which later became known as “tigris” in various other languages. So, to summarize, the name Tigris in Ancient Greek does not refer to an animal, but is rather the name of a river.
