Bhai.1) Hans does not know how to speak English yet.
Could you also say " Hans does not know how to speak English already." if you say that the word "already" does not
refer to the whole sentence but only to that bit "...how to speak English." - in the sense of " how to already speak
When it comes to forming a question like " Does Hans know how to speak English yet?", could you also say " Does Hans already know how to speak English?" if a positive or affirmative answer is expected by the person asking the question, as
is the case with "some" in questions like " Would you like some wine? " because a yes - answer is expected? Yes.
Is the word " already " sometimes used in spoken English although "yet" would be correct? Possibly.
Looking forward to your answers!
