"That is your book."
Translation:वह तुम्हारी किताब है।
When would you use tumari or tumara...when referencing a book. When the sentence on English does not indicate male or female?
Every noun in Hindi has a gender, most words that end with आ are masculine, and most words that end with ई are feminine. The rest you just have to memorize, in this case, book (किताब,) is always feminine, so you need to use तुम्हारी.
