So far, you've learned Ech and you've learned how to say Tall but you haven't learned how to describe yourself as it.
The word am is sinn
1 translation: I am tall
But how do you describe someone else?
The phrase You are is Du bass
2 translation: You are a donkey
She is Si
He is Hien
We is Mir
Just like in other Germanic languages, "they" and "she" are the same word. (Zij / Zij in Dutch) (Sie / Sie in German)
So, They is Si
If you can remember that the words The man is are De Mann ass, you might realise that Are are is kinda similar.
The phrase you are is du bass
3 translation: You are tall
This works for singular but pl. you are is dir sidd
You say hien ass and si ass but if you're saying they are, the phrase is si sinn
to have is hunn
4 translation: I have
you have (sg.) is du hues
5 translation: You have a donkey
