मत a Hindi translator I use says this is "vote". Is that true?
Yes, that word has two meanings. "Don't" and "Vote". There are many such words in Hindi.
Yes
Uski = her Use = to her Why here we use uski
Because the sentence would be literally translated as: her speech don't listen.
You can also say 'mat suno uski baat'
And thats kinda native too
You can speak like that but That's an unsual speech order
That comes out a bit rude by the way
