It is catwoman who organizes these classes so it is better to ask her.

The classes are not something where we teach the learners any lessons. The learners are studying the topics themselves and trhen they do the exercises. We only check the exercises and correct them. We also answer questions if there are any. The good thing is that there are some nicely written exercises specially for this project but of course they are available to anybody from the two links in my previous message. Bye. 

You cannot reserve a place. When it is announced that new groups are starting and students are needed, you can respond to that thread in the forum to join the group.

How do i say ´thats´s why´ in the sentence ?

At homework i got  mixed up,and i have put çünkü in the place where i wanted to say ´thats why´

 İ wanted to form the sentence the other way.

For example,

İşe geç gittim,çünkü otobüs çok geç geldi.

İf i want to say it the other way around,can i ?

Otobüs çok geç geldi,´thats why´ işe geç gittim.

Would it be bu niye ?

I think "işte bu yüzden" is what you need.

Canlı,

The other way around of çünkü sentences is build with "-diği için".

Example:

İşe geç gittim, çünkü otobüs çok geç geldi.

Otobüs çok geç geldiği için işe geç gittim.

1. Çok çalıştiğim için bugün çok yoruldum.
2. Çok yağmur yağdığı için ıslandım.
3. Arkadaşlarımla Türkçe konuşmak istediğim için Türkçe öğreniyorum.

We add the personal suffix to diği when needed,its not fixed rule to ´-diği´ only,yes ?

 İn a way we can say "-diği için" has the meaning of ´because of ´ or something,right?

1. Because of my worked hard,i was very tierd today.
2. Because of the rain it rained hard i got wet
3. Because of my desire to speak Turkish with my friends,i have learnt Turkish

A note,here

i have noticed you havent used comma with "-diği için´´ and at same time we use it with çünkü,not like the case in English,i guess we use the comma in English in both ways.

İs that right ? Yes?

diği has already a personal suffix. It has the third person posessive suffix. We use possessive suffixes here. Here is a full conjugation:

ben geldiğim için

sen geldiğin için

o geldiği için

biz geldiğimiz için

siz geldiğiniz için

"onlar geldiği için" or "onlar geldikleri için"

Compare this to any possessive suffix: (It is exactly the same)

benim evim

senin evin

onun evi

bizim evimiz

sizin eviniz

"onların evi" veya "onların evleri"

This is possible but I wouldn´t put it that way. The -dik suffix has many different usages. This is only one of them. Here are a few:

geldiği için : because he came

geldiği zaman: when he comes

geldiğinde: when he comes

geldiği gün: the day he came/comes  

geldiğimiz uçak: the plane we came in

With için sentences you don´t need a comma. With çünkü sentences it is a matter of taste. 

 When we want to say ( let someone get in the car ) we use binmek ,take someone with us in the car ,we use almak

So,when we want to say (we give someone the car ´he will drive it´ ) we use vermek ?!

Also,when do i use the yordu combination ?

When its something happened in the past and still continuing till now ?

 And i also found those here

http://www.turkishclass.com/forumTitle_312_-1

As i understand now,there is no zaman eki with the dIk form

But we understand the tense of it from the sentnce itself,yes ?

We can form it

Verb stem + dIk + iyelik eki + any other suffix that we need to use ´accusative,locative,...ect´

Yes ?

So,i wont be wrong if i assume that de in gittiğimde for example is the locative case ?

When i was doing section 6 homework,imir,istik kepi,i thought that we dont have home works about the negative question

So,i opened WinMekMak to check it

And there i found there there are cases with sen and siz in the optative tense as well

Gidesin

Gidesiniz

But with o and onlar its not recommended!

And when i opened here

http://www.turkishclass.com/forumTitle_2565

İ found there are none !

Another point,is the meaning .

Getsin....talking with someone about x and telling an order that x should do.

Getmesin.. ,,  ,,  ,, ,,  ,,  ,,   ,,,   ,,,  ,,,, ,,,,,  ,,,,,, ,,,,,, ,,,,,, ,,,,,,, ,,,,,,,, ,,,should NOT do.

Getsin mi ? also same but instead asking if he should go...in a friendly tone,or in an order tone ?

Getmesin mi ?..same as above but with negative,again,is it a friendly tone or blaming tone ?

I´m sorry but I won´t be able to help you anymore. You can read more details here:
