Difference between Ihr and dein?

Could someone tell me the difference between "Ihr" and "dein"? Thanks, Behzad

Hi Behzad, 'dein' and 'ihr' are pronouns. 'Dein' is 'your' and the genitive form of you. There are two forms of 'ihr', one is the dative form and means (to) her and the other the genitive form meaning her. The question word in the dative is 'wem' (to) whom). The question word in the genitive is wessen (whose). Examples: Das Auto bereitet ihr Probleme-> the car is causing her trouble. Whose car is causing trouble? Her car. Let me know if you need more examples Greetings Paul

Hello! Dear Paul, If I say: Wie heiBt Ihr Bruder? Oder: Wie heiBt dein Bruder? OR: Wie heiBt Ihre Schwester? oder: Wie heiBt deine Schwester? What is the difference? Is there any concept of Formal and Informal? If there is, then which one is a FORMAL way and which one is an INFORMAL way?

Hi Ahmar, Sorry for the delay. The examples 'Wie heiBt Ihr Bruder?', 'Wie heiBt Ihre Schwester?' can be referring to the Dative form of the formal 'sie' or it can mean 'her'. 'What is the name of her brother?' 'Sie' and 'ihr' the formal form of 'you' is used when you wish to be polite or show respect to an individual or a group. You might use it with strangers, the elderly, teachers or authority figures. 'Dein' and 'deine' is iformal 'your' in English. Hope it helps!

Sorry I missed that one too or I could have answered it.
