We just learned that I am happy in Greek is Είμαι χαρούμενος (eímai charoúmenos), and you are sad is Είσαι λυπημενος (Eísai lypimenos).
Now let's learn how to say He is angry.
Είναι θυμωμένος (Eínai thymoménos)
We can break it up into two words:
He is - Είναι (Eínai) - sounds like EE-nay
angry - θυμωμένος (thymoménos) - Sounds like thee-moh-MAY-noh-ss
So all together Είναι θυμωμένος (Eínai thymoménos) sounds like EE-nay thee-moh-MAY-noh-ss.
