Kernewek (Cornish) I am hungry

Dydh da!

In the course Go Cornish Intro , lesson 4 I am/ I need there are two sentences with the exact same meaning I guess or is there any difference?

a) gwag ov vy
b) yma nown dhymm

I was surprised when I chose for b) the translation I’m hungry and it came out as wrong and the correction was “I am hungry “.

By the way, where is everybody? Nobody learning Kernewek here?

Many thanks for the person or persons who took the time and effort to make this great lessons. Meur ras!
