Merhaba,

I have a lot of difficult with the word olmak and espacially olması, olmasın and actually also a bit on olan.

olması:

Does this mean: let it not be? or: he or she does not become?

Or does it mean: He/or she is??

Is this a positive or negative word of olmak?

because sometimes i see words like olmama.. and then like olmaya but then also a negative word like olmasin(or is this positive)

I am very confused, please help.

I never heard "olması". There isn´t in Turkish. It is like this;

Ol-mak = To be = Verb / Fiil 

Olsun = Positive and means "He/She/It be!" It´s a Imperatives. Think like;

"Be doctor!"="Doktor ol!" I said you this. Bu How will say it to he/she/it.

like this

"Be doctor!"="Doktor olsun!" I said to him/her/it.

I can´t speak English very well sorry. :/

But negative;

Ol-masın = "Don´t be!" for He She It

Do you understand me

There is "olması" in Turkish. Literally it means "his/her/its being"

ex: Notlarının kötü olması senin suçun.

Literal translation: Your grades´ being bad is your fault.

Normal translation: It is your fault that your grades are bad.

ol - ma - sı

-ma suffix doesnt make verb negative here because this -ma is another suffix which makes verbs function like a noun. That way an action can be owned in Turkish with the help of other suffixes.

Thanks for your answers.

But with ol-ma-sin, sin is the ´you´ suffix

ol-ma-si, si = third person.. but why is ma negative at the ´you´ suffix and not with the third person suffix

I´m still at the beginner stage but gokuyum pointed out that they were two different suffixes. One is the negative suffix and the other I think is called the short infinitive. 

-ma suffix doesnt make verb negative here because this -ma is another suffix which makes verbs function like a noun.

so you need to deduce from the context if it needs to be functioning like a noun right?

 olmasin = negative, olmamiz = positive again.. How can we find out the difference easily?

and what would be the negative form of olması? olmaması ?

-sın is not ´ you ´ suffix here, actually it is third person singular "he/she/it" suffix. Why? Because you dont use any suffix for "you" when you give a command to ´you´ like in English. You only use verb root to give a command to ´you´  come/ gel, go/git. But when you give a command to a third person you use -sın suffix or its variants:

Gelsin means "let him/her/it come"

Olsun means "let him/her/it be"

You use -sın suffix for ´you´ in tenses except simple past tense and you dont use any suffix for he/she/it in tenses.

Gelirsin : you come.                     Gelir: he comes

geliyorsun: you are coming.          Geliyor: he is coming

geleceksin: you will come.             Gelecek: he will come

geldin: you came.                         Geldi: he came

gelmişsin:you had come.               Gelmiş: he had come.

Correct. Ol - ma - ma -sı 

ol-  is verb root

first  -ma makes the verb founction like a noun

second - ma makes it negative

- sı is possessive suffix
