Still more & yet more
Please, when do you use 'still more' but when 'yet more'?
As an example: he grew still more.. umm... depressed :) Can it be said with using yet more in the same meaning or there will be a different meaning with 'yet more'?

Answer

When  "still" is used for describing sth. that has not been done,u can say:She still hasn`t come back. "Still" must be put before "hasn`t"  (negative helping verb)
But,"yet" is more used in the negative sentence.

Answer

Still is only used in affirmative sentences.For example,She still is here.
And yet is used in negative sentences and questions.For example,
She hasn`t left yet. 
Has she left yet?
