I think the explanation is here:

When tense/aspect/modality markers co-occur they appear in the order given below (Göksel – Kerslake). Copular markers (group 4) are composite. They consist of the copula -(y)- < *-i- and the grammatical marker –DI, -mIş or –sA. Copular markers attach to

1. nouns

2. verbs that contain one of the tense/aspect/modality suffixes in group 3

So, in görseydim there is a suffix -sA- from group 3. That is why in further affixation it is treated like it was a noun and the copula -(y)DI-  -  buffer included  -  is used with it.

The situation would be the same in gördüysem btw  -  -DI- from group 3 and -(y)se- from copular markers.

I have understood the buffer is a relic from the old *er- stem, so no wonder.

Ayasofya´nın temeli Arşimet´e mi dayanıyor?

Ayasofya birçok açıdan hayranlık uyandıracak bir yapı ama buradaki önemli nokta diyagramlar ve sayılarla tasarlanmış olmasıydı. Bu kesinlikle matematikçilerin işiydi. Hagia Sophia is an awe-inspiring building in a lot of ways but what is important here is its being projected with graphs and calculations. It was certainly work of mathematicians.

When Emperor Justinianus I wanted to build the greatest building on earth he hired two scientists, the mathematician Tralles of Anthemius and the physicist Isidore of Miletus:

Antik dönem kaynaklarında Anthemius ve İsidoros için mimar yerine daha çok mühendis anlamına yakın olan mekhanikos veya mekhanipoioi kelimesi kullanılmıştır. Trallesli Anthemius çalışmalar başladıktan kısa bir süre sonra ölünce, Miletli İsidoros kiliseyi tek başına bitirmiştir. İsidoros’un hocası olduğu sanılan Anthemios mekanik cihazlar, hidrolik konular üzerinde çalışan bir matematikçi ve fizikçiydi. İsidoros’un parabol çizmeye yarayan bir pergel icat ettiği bilinmektedir. In the sources of ancient history instead of being called architects Anthemius and Isidoros are called ‘mekhanikos’ or ‘mekhanipoioi’ whose meaning is close to engineer. As Tralles of Anthemius and died shortly after the works had begun, Isidore of Miletus finished the chuch alone. Anthemius who is believed to have been Isidore’s teacher was a mathematician and physicist who worked on mechanic apparatus and questions of hydraulics. It is known that Isidoros invented a compass which could be used for drawing a parabole.

Isidore was a specialist of Archimedes´s mathematics and he probably made some corrections to the manuscricpts of the ancient master. His three codexes were kept in Istanbul, the last one until 1912, and recent research has proved their ideas are manifested in the engineering of Hagia Sophia. My layman thinking says it must have something to do with the greatness of the dome because Archimedes’s most important achievement was to count the volume of the sphere. On his own request a sphere and a cylinder were put in his tomb in Sicilia as a symbol of his life’s work.

May I ask?

Doesn´t this mean ´you are not in a position to help me´? Or am I missing something?

What about benden iyilikler isteyecek pozisyonda olmadığını düşünüyorum? No?

A human being can endure serious traumas if his eye doesn´t remind him of it all the time.

I think there is a deep wisdom in it. But the problem in these sayings is they are syntactically reduced into something so short you have to fill great gaps of meaning just in your mind. The second one would have been almost impossible for me to understand.

But if you for instance saw her all the time but couldn´t approach her it would be worse wouldn´t it?

The meaning is not so clear I must admit. This is how TDK explains two similar sayings:

§  göz görmeyince gönül katlanır
 yakınımızda bulunmayanların özlemine, acısına daha kolay dayanabiliriz.
Atasözü

§  göz görür, gönül katlanır
 kişi, sevdiği bir kimsenin uzak yere gitmesi durumunda onunla görüşmekten umudunu keser, ayrılığa katlanır.
Atasözü

Isn´t it like what you can´t see you forget or if you don´t see someone you get used to his absence?

In your example talk is about coffee. Kahve is the main word or the governing word of that compound. Türk adds something to the meaning, modifies or specifies it.

Point 1:

If the modifier is an adjective no changes happen in the main word of the phrase. Note that what is an adjective in Turkish grammar is not always translated into English with an adjective:

                             kaybolan cüzdan ´the lost wallet´

                             bahçeli bir ev ´a house with a garden´

                             sokaktaki kedi ´the cat which is in the street´

                             mavi gözler ´blue eyes´

Point 2:

If the modifying word is a noun (like in your example, sakine) the governing word is marked with a possessive suffix. If it has no real owner in the context (like okul çanta|m ´my school bag´ ) the modifier is marked as the owner and in that case it is sg or pl 3rd (okul çanta|sı ´school bag´ ).

The modifying noun may be in either genitive or nominative form. This is sometimes difficult for a learner to grasp but as a general rule genitive denotes a real possessive relation between the modifier and the main word as nominative ties them together on a more abstract level. Thus,

                               evin bahçe|si ´the garden of the house´

                               gül bahçe|si ´rose garden´

It is not quite this simple. For more detailed information look here:

(Your question is quite short and I am not sure if you wanted to know why the suffix is there or why it looks like it does. Anyway, this is my share as another learner, I hope a native will check the examples.)

Göz görmezse gönül katlanır, doğru mu?
