Let me first say that I miss you very much and that you are always on my mind.
Öncelikle seni çok özlediğimi ve her zaman seni düşÃ¼ndüğümü bilmeni isterim.

I can't figure out how özlediğimi, seni düşÃ¼ndüğümü and bilmeni are formed, and especially I'm pretty confused on -i suffix at the end of the verbs.
Can someone help me out?
Thanks in advance.

Nobody knows?

Well then I have to reply to the post on my onw so as to make it on top.

I'd love to help you but I have no idea.

But at least I can help you by keeping this post at the top of the forum
I'm curious about the answer as well..

Thanks Elisa.

I got it another hit.

There is nothing special here. It's just the accusative case suffix at the end.

Bilmek (to know) is a transitive verb and takes direct objects.

Özlediğimi bil.
Know that I miss you.

Seni çok özlediğimi bilmelisin.
You need to know that I'm missing you a lot.

Seni çok özlediğimi ve her zaman seni düşÃ¼ndüğümü bilmelisin.
You need to know that I'm missing you a lot and thinking about you all the time.

Seni çok özlediğimi ve her zaman seni düşÃ¼ndüğümü bilmeni isterim.
I want you to know that I'm missing you a lot and thinking about you all the time.

Thanks alot,erdinc.

It's pretty clear to me

lets make geyik
seni cok özledim = i have missed u much
seni cok özledigimi biliyor musun? = do you know that i miss u much?
seni düsünüyorum simdi = now i think u

seni özlemek cok güzel = its so nice to miss u

beni özlüyor musun? = do u miss me?
