Nouns. Tip #4: Nouns as Objects
Nouns can also be objects of a verb in a sentence. An object can be either a direct object (a noun that receives the action performed by the subject) or an indirect object (a noun that is the recipient of a direct object).
Example: Give the books to her. – Отдайте ей книги.
Books is a direct object (what is being given) and her is the indirect object (who the books are being given to).
