Merhaba!

I am a bit confused with the suffixes. In my book there is a tamamlayıcı bilgiler but no meaning is added so it is hard to figure out what it means exactly.

burası-??? this place???

buraya-to here

buradan-from here

burayı-???

burada- in here

There is a question : Burası neresi?- What is this place? (at least I think it means that)

orası-???

oraya-to there

oradan-from there

orayı-???

orada-in there

şurası-???

şuraya-???

şuradan-???

şurayı-???

şurada-???

How to use lı, (-li, -lu, lü  and -sız, (-siz, -suz, -süz )

Is it `with `(lı ) and `without `(-sız) ?

It is very hard to learn alone. Please If anyone could help would be appreciated. Teşekkür ederim

Oh, thank you for the insight! Your post is very helpful!

Can you tell me about burayı and the rest as well later on when you have time?

I think Burayı is when you are using here as an object:

Burayı sevdin mi? -i accusative (Did you like here?)

That is right explanation. 

With some verbs which requires an accusative marking we add -I [i,] in the end of "bura" some of those verbs :

-i bilmek  [ to know something]

- i sevmek [ to like/love something]

- i  görmek [ to see something]

- i temizlemek [ to clean something]

-i  satmak  [ to sell something] [ if it is a definite object]

Burayı bilmiyorum. ---> I don´t know here.

Burayı  sevmiyorum. ----> I don´t like here.

Burayı daha önce görmedim. ----> I haven´t seen here before.

Burayı temizle ----> Clean here.

Burayı satmayı düşünüyorum. ---> I am thinking to sell here.

Note: "y" between two vowels funciton as a buffer letter to connect two vowels.

How to use lı, (-li, -lu, lü  and -sız, (-siz, -suz, -süz )

Is it `with `(lı ) and `without `(-sız) ?

We can also use plural forms of those words

Buralar, Oralar, Şuralar

ora + lar [plural]

oralarda hayat nasıl ----> how´s the weather over there ?

Bura + lar 

Buralarda hayat zor. ----> Life is hard here.
