This is the 948th most frequent Armenian word.
քեզ
"Քեզ" means "you" (singular, informal, objective case) in English.
In this sentence, 'քեզ' is used as the object pronoun meaning 'you' in the accusative case, indicating the person whom the subject loves.
Ես քեզ շատ եմ սիրում։
I love you very much.
Here, 'քեզ' again functions as the object pronoun 'you', specifying the recipient of the action of showing.
Ես քեզ ցույց կտամ ինչպես պատրաստել այս ուտեստը։
I will show you how to prepare this dish.
In this example, 'քեզ' serves as the reflexive pronoun 'yourself', pointing to the individual who will keep the book.
