Hindi verbs have to be conjugated to reflect the subject of the sentence. Let’s look at the Hindi verb “to do” in the masculine, using the singular and plural forms.

I do : मैं करता हूँ

You do : आप करते हैं

He/It does : वह  करता है  

We do : हम करते हैं

You (plural) do : आप  करते हैं

They do : वे करते  हैं  

The verb “to do” in the feminine will only be slightly different from the masculine, so please pay attention.

I do : मैं करती हूँ

You do : आप करती हैं

She/It does : वह करती है

We do : हम करती हैं

You all do : आप करती हैं

They do : वे करती हैं

कर = to do. Now you can see for yourself as to how the verb changes in respect to gender and number.
