Translation:She is my mother.
But why I cannot hear how the words should be pronounced?
Unfortunately that doesn't work yet
I REMEMBER WHEN DANY SAID SOMETHING SIMILAR!
"Valryian is my mother tongue"
Valyrio muño ēngos ñuhys issa. ("Valyrian is my mother tongue")
"This is my mother" should be OK, as there is no "she" in the sentence, I think.
I'm saying that's what she said on the show
