Now that we have mastered plural verbs, we have to have plural nouns to accompany them (subject/verb agreement, remember!) With just a quick ending change, a noun can become plural. What is important is that you put the correct ending based on DECLENSION!

As we've read in our culture, Plautus was one of the most prominent playwrights in Ancient antiquity. His plays usually followed the same pattern: a young man from a respectable family who lives a wild life. He is often in debt and in love with a pretty but unsuitable slave-girl. His father, who is old-fashioned and disapproving, has to be kept in the dark. A cunning slave usually helps him. Eventually it is discovered that the girl is freeborn and from a good family, so they are able to marry. Does this sound familiar...?
