"Grandmother is writing in the book."
Translation:दादी किताब में लिख रही है ।
So ह is also possible here? I thought that when talking about a mother, father, grandmother, grandfather and so on, we always use the plural form.
Yes, I am interested in this question too. Can a native speaker answer it?
Me too. Besides i wonder why किताब is not किताबें since there is a postposition after it (में)
किताब is in the singular oblique case. It's the same form as in the direct case. किताबें is in the plural direct case.
