This is a rather elementary question but I'm revising vocabulary in LLPSI Book 1 and am looking at the months. In Latine Disco Orberg tells us that Latin months are adjectives. But in the vocabulary at the back of the book he gives information on all the months as if they are nouns: e.g. Februarius, -i (m) etc....
What am I missing? Is it that Mensis is masculine and so all months are masculine adjectives....?
