I have tried to read carefully everything that natives have said in this thread. To sum up everything as I have understood it I noticed the following:

The problem about the structure 35 yaş|ı|n|da|yım was the adjective nature of Turkish numerals. In a compound they don’t demand a POSS in the next noun. For a while I was suspecting this because all adjectives as a matter of fact can be used as nouns. But it seems that numbers are especially sensitive adjectives: they hardly ever stand on their own, there has to be a noun after them (tane, kişi). The problem remains.

As the POSS in yaş|ı|n|da|yım can’t be motivated by the compound it has to be motivated by something else. I think there are two alternatives that have been mentioned in the course of this discussion. Actually one of them has been shot down already but I still try to rise it up:

1. Analogy of cases where the expression of measure is between the numeral and the quality, like 1.80 (meter) boy|u|n|da|yım.

2. Ellipsis.

a) There is something that we can’t see between 35 and yaşındayım. A measure. yil, yaş? In this case yaş in yaşındayım wouldn’t mean ‘year’ but ‘age’ (which is its first equivalent in some dictionaries). The structure would be like in the boy thing in nr 1.

b) There is something that we can’t see before 35. A genitive marked noun: something like yaşın, yıllarımın, zamanın… I suggested this but scalpel said in that case the numeral should be the ordinal 35inci. Is it impossible to imagine that it once was ordinal but it was simplified? In other languages I have seen processes like this. It seems like a very logical development because the ordinal marker is nothing but a burden from the point of view of information. But if something like this really happened there should be marks of it in old litteral language, I suppose.

My knowledge is limited but a learner can speculate as much as she wants. If she has the guts.

Seems there is a hole in knowledge from these poems. As yet I had not found any sources that tell what languages were being spoken in the later years, but I had figured Arabic was being spoken in the Ottoman empire at least for most of it, Or was this Turkish being spoken up until the last Sultan (1913)?

Curiosity of Türk history came with learning the language, for me at least. Ive been reading about ´Ottoman´ culture and military history (because of this I wish I had a way to see that film Fetih 1453) 

Is this the same person whom the Arabs call Muhammad il-Fatah (“Muhammad the Opener” ) and who conquered Istanbul from the Patriarch of Constantinopole in the 15^th century?  -  I didn’t know he was a poet but little I know.

Poetry was very much appreciated in early Islamic societies. It has been told that some of the Prophet’s closest people, for instance his wife Aisha, had great knowledge in poetry. This side of Islam, appreciation of scholarship and tolerance of worldly life, is unfortunately not very much stressed by islamists of these days.

This poem is real lyrics in the sense that it doesn’t manifest anything but reflects a person’s inner life, insecurity and the psychological dissonance we all struggle with. Thank you for adding today´s portion of culture, gokuyum.

My Guess:

Ok, you say we want to stay mysterious. No no, I made a translation, only the two of mine was were only a gesture.

I asked because I found this in the dictionary:

           Bundan sonra ne Sarıyer´e, ne Marıyer´e gider; hiçbir yere gitmez.

There seems to be three different negations. Is it wrong?

Biri asla öğrenmek için fazla yaşlı. -"One(someone) is never too old to learn." 

I had thought to use -çok initially but none of it´s uses seem to fit in with "excessiveness" which  is how "too" is being used here. My instinct to use "-mek için" simply because I was not sure how to tie the excessive adjective in with the verb. Another example:

"The kitten is too small to jump up on(to) the bed."

Where you have the excessive adjective (too small), followed by verb infinitive (to jump) Though I know how -mek için is supposed to be used

Merhaba!

Could you tell me how do you build in Turkish impersonal constructions with "how to..."?

For example: I don´t know how to say this in Turkish.

Türkçe bu nasıl söylenir bilmiyorum.

or maybe passive?

Türkçe bunun nasıl söylendiğini bilmiyorum

Gokuyum, may I ask if you don´t mind why did you edit this "short message" four times in 25 minutes?
