"A strawberry is a fruit."
Translation:Frago estas frukto.
Why isn't it, "Frago estas frukton"? The whole add an "n" part is very confusing. Sometimes the n is added, sometimes it's not. Sometimes it's added on some of the object words in a sentence, while other objects in the same sentence don't have it. Duolingo expects us to just pick up on these unexplained rules. But there should be some type of explanation in a note or something before the lesson. Can someone explain why some sentences use the n and some do not? Thanks in advance. (Sorry if I sound whiney. It's just a bit frustrating. I want to learn the correct rules, so I can practice right, instead of just guessing each time.)
