'simika' must be '십니까'. 십니까 is a way to ask something. You need a root of Korean verb and add 십니까 to ask something. Ex) 하다(do)+십니까? = 하십니까?(do?), 보다(see)+십니까?=보십니까?(see?)

"simNika" is added to the end of a sentence to make it a question. It is like replacing the question mark, ?, in English with 십니까.
