" Language X is more difficult than language Y". Thanks

Dil X,dil y´dan daha zor.

My try

X-ce(ca) Y-ceden (cadan) daha zor. 

X dili Y dilinden daha zor.

Zeytinne´s translation is used for specific languages. We don´t use "İngiliz Dili" or "Yunan Dili" in daily speech for specific languages, this structure is only used to express linguatic studies of universities:

İngiliz Dili ve Ebediyatı: English Language and Literature.

Yunan Dili ve Edebiyatı: Greek Language and Literature.

X - (ce, ca, çe, ça) Y - (ce´den, ca´dan, çe´den, ça´dan) daha zor(dur).

(X,Y : the name of nation; French: Fransız; Arabic: Arap, etc...)

Fransızca İngilizce´den daha zor(dur): French is more difficult than English.

İngilizce Fransızca´dan daha kolay(dır): English is easier than French. 

Thanks

Of course that´s how I would have translated it had he asked for specific languages!

I did instead of you for other possible meanings...

I hope you can guess why I had translated like that, of course to get rid of these "ce-ca"s since specific language is not mentioned, of course it is used in Turkish, we use as well, but mostly formally, and since it was translated before me, i proposed another option...

I don´t want to be misunderstood, so I´ve changed and corrected my message.

Thanks.

Sorry herkes! I have provided further clarification

" Javanese (language) is more difficult than Indonesian (language)"

Thank you all so far, and sorry to rack your brains !
