We just learned that in Hindi I am happy is म्हानै खुशी होई (mhaanai khushee hoee),
you are sad is आप दुखी हैं (aap dukhee hain),
and he is angry is वह क्रोधित है (vah krodhit hai).
Let's learn how to say they are excited.
They - वे (ve) - Sounds like vay - 文A
Excited - उत्साहित (utsaahit)- Sounds like oo-t-sah-hit - 文A
Are - हैं (hain)- Sounds like hay - 文A
All together वे उत्साहित हैं (ve utsaahit hain) - Sounds like vay oo-t-sah-hit hay
