yeah Mltm youre right, but what misled me was the usage of the ´Ş´, so to me  if they  would use ´Ş´ why wouldn´t they use ´Ü´?

That´s how I got confused and thought it had to be musun and not müsün

Can you explain what you mean, please??

 difference is much more than just the script used. The vocabulary is very different.

e.g. east and west in modern Turkish is doğa and batı. In Ottoman Turkish it is garp and sarp.

Quote: Reyhan

These words are not respecting turkish vowel harmony too 

So? What´s your point?!

As I always told my students ´ every rule has its exceptions´ 

It´s not about jumpıng off a bridge and following, we´re talkıng about a language here, and languages change slowly so if Turkish people choose to say MEŞGUL MUSUN instead of MEŞGUL MÜSÜN then they´re 100 per cent right since they´re the native speakers.

Therefore you´ll have to follow, nobody these days uses thee and thou which were commonly used just about 200 years ago, and why is that? Because languages undergo changes.

Just to be fair, I did a bit of research regarding this issue, well you´re right it ought to be ´Meşgul müsün´ rather than ´musun´. Although I must admit that this is the first time I encounter it. However, it seems that the newer generation prefers the latter one  

yeah.. theyre the same words in arabic... the root is originally arabic

 cami is an arabic word and it means in arabic the thing which contains more than one thing

or place which contains amore than one section

this the genral mean in dictionary

By the way, as far as I know you can omit "daha" word when comparing two things or persons, which/who are mentioned in the sentence. I´ve read about it in G.L. Lewis "Turkish Grammar" - however, I have only access to old edition of this book (it´s about 40 year old), so I´m not sure if it is still correct in modern turkish to skip word "daha" in this way. Maybe someone more advanced can say something about it ?
