There are two common ways to talk about age in Hindi. One way uses the word उम्र age. This means lifespan in the sense of how long somebody has been alive, so it is only applicable to people and animals. This is the most common way to ask how old somebody is:
In reply you have to say literally ‘I am of so many years’, and the ‘of’
की agrees with the gender of the person speaking.
If by chance two people of the same age were speaking they might also say.
Old, in the sense of the age of an object, is expressed by using the adjective पुराना old. For instance:
Old, in the sense of a long lasting relationship, is also expressed using पुराना old. Note that talking about a friend this way would refer to them being a long term friend, not an old person, but old, in the sense of aged, is expressed using the adjective बूढ़ा aged.
old, long lasting
aged, senior, old
friend (this used to be only for male friends of men, and did not include female friends of men or women, but its use is mostly now like English friend. However, note that a female friend of a woman is referred to as a सहेली )
