As caliptrix said the "-(y)ip ... -ma" is a noun clause that expresses "whether or not" so you´d use it to say, for example, "whether or not you´re coming in tomorrow, I´ll make a cake".

The first verb stem takes on the -(y)ip suffix, whereas the second verb stem, after you add the negative -ma/-me, can take on a variety of suffixes, such as, for example: -dik, -y(acak), -ma, -mak, etc. 

You´ll see this usually as an object of verbs of "knowing" - bilmek, anlamak, fark etmek, etc., or also söylemek or sormak. In English those would be the type of expressions when you say: I don´t know whether or not s/he ...., I asked him whether or not ...., etc.

So the sentence that you wanted to use (with slight corrections): "Yarýn gelip gelmeyeceksin, bir pasta yapmayacaðim", would translate to "Whether or not you´re coming tomorrow, I´m not making a cake".

I read somewhere that meþgul is a borrowed word from arabic. Some of the arabic words don´t exactly follow the "Turkish" rules (methinks).

Thank you for taking the time to explain it, I think I understand it much better now.

Thanks. I don´t mean to be picky either, it just helps with the learning to have the details

Also, I´m wondering if "her þey olur mu?" would have the same meaning as "her þey yolunda mý?" - I looked up yolunda in the dictionary (new word for me ) and it seems fine, I´m just wondering if there´s a difference in meaning between the two?

Should I be posting questions like this in the language forum instead of translation forum?

Thanks again.

Just a couple thoughts/questions:

I think meþgul doesn´t obey vowel harmony, so it probably should be meþgulsündür.

Also I´m thinking "to hear from you" would be translated better as "senden haber almak" istedim - "sesini duymak" is more like "to hear your voice".

Also, I´m wondering if "Herþey olur mu?" wouldn´t be a good translation here.

I´m just a beginner, so I might be wrong here, it´s just what came to my mind when looking at this post.

It is what you make it.

Anyway, hugs Femme, obviously it´s hard to be you. I should be more understanding.

It´s hardly surprising, you don´t seem to be capable of any other emotion than hate in some form or other. Why should Decemeber be any different?  

I forgot to give you my birthday present, here it is:

And me (that´s the scary part lol )

Thank you for the clarification. What confused me was that I was thinking genis zaman to be the tense which you use to nicely ask people to do things for you, I just didn´t realize right away it wouldn´t work if you´re asking if you can do something yourself.

Again, thanks for the explanation and corrections Very helpful.

Actually never mind, I just realized that with the wide tense it would translate into "Would I speak with Ali?"

Disregard my previous post and thanks for the corrections
