Today's word is PATRIA (gen. patriae), meaning "fatherland" or "homeland, native country." This is actually the feminine form of an adjective, patrius, which you can see in other uses as well. For example, Cicero can refer to the patrius sermo (what we would call your "mother tongue") and a nomen patrium is a patronymic, a name based on your father's name (as when Aeneas is called Anchisides, from the name of his father Anchises). Far and away the most common usage of this word, however, is as the feminine noun patria.
