3rd Declension Adjectives - Examples and Practice

Let's explore what these adjectives look like fully declined. We'll look at one adjective from each termination. Remember that when we decline an adjective, we list the forms for each case in all three genders: masculine, feminine and neuter. However, double and single termination adjectives do not require listing all three: masculine and feminine forms are identical for these adjectives, so we can list the Masculine and Feminine forms together.
