yah i do know this..

i dont think u know what i mean..

take the title of the thread as an example..
merak ediyorum da
here doesnt the "da" add sth. onto the sentence??

well? can i have some help please??

thanks

lets take the title, merak ediyorum da..

here the da highlights that i am doing something for a reason, ie. the verb before it. thats correct yeah?

im not sure however, whether or not da is just used as a word or as some kind of changeable suffix which follows vowel harmony..??

turkce konusurken, sinema kullanirim ama bakiyorum da sinama da kullaniliyor...? hangisini kullanabilirim?
simdiden tsk. ederim

hey.. by the way..
if on the tape which my turkish will be recored on, i am speaking in a more informal way will this effect my mark?
for eg: geliyom, gidiyom etc.
also, if i am given a scenario where i have to reply to someone should i use the formal version?
for eg: ... soyluyorsunuz??

thanks in advance
