Root Explanation

Eutherian → It is formed from "eu-" (meaning good or true) and "therion" (from Greek "θηρίον", meaning beast or animal). The term refers to the group of mammals that are characterized by a more advanced form of development, hence the idea of being a 'true' or 'good' beast.

Memory Tip

Think of 'eu-' meaning good and 'therion' meaning beast — this helps you remember that eutherians are considered the 'true' or 'advanced' mammals.
