So far we
have learned the present imperative forms
When we want to ask someone to do something in the future, then
we may use the future imperative forms:
A. Familiar future imperative = infinitive, e.g:
तुम मेरे घर
to my house tomorrow:
future imperative = regular polite imperative +third person sing
future ending, e.g.:
आप मेरे घर
come to my house tomorrow.
future imperatives are always masculine third person singular;
they never change under any condition.
