What is a declining noun?
So, when we decline a noun, this means that we add the appropriate case ending to it. Modern English does not have a very developed declension system, but we do still use some case endings. Personal pronouns are a great example. Consider the following forms. he = nominative / subjective case.
How do Latin adjectives decline?
Like nouns, adjectives in Latin are declined. The vast majority take either the first and second declension (antiquus -a -um) or the third declension (ferox, ferocis). All such adjectives must agree with the nouns they describe in gender, number, and case.
