Sooo... Is the small book not accusative?? It must be, right?
I read the book.
The book is accusative because of the verb.
I am the man.
As if the man isn't accusative now.
If I'm correct, I've seen this in multiple questions already, so I hope we can make a change.
For people that don't fully understand: Accusative case is when it gets an n, here it turns into malgrandan libron.
An example in English:
It is him.
It wouldn't be it is he, since he is now in the 4th case, so it turns into him.
Although most people understand this, just for the younger people learning Esperanto. (even though I'm 14 myself ;))
Estas means is, and is is a linking verb in English. When you have a linking verb a good way to check it is saying to yourself does the noun equal another noun or adjective in the sentence. Example: She is a girl. She is the subject/noun. A is always an adjective since it is an article. Is is a linking verb. Now we ask ourselves, what does she equal? We now know that she equals a girl. That makes girl the linking verb compliment, and since it is a noun it is a linking verb compliment noun, instead of a linking verb compliment adjective. If you don't understand. I can explain more, just write on my page. Hope this helps!
