IMPERATIVE - EMİR KİPİ

We use it when we want to command someone. 

Yapmak -> To do

I -> You can not command yourself.

YOU -> Yap! (Nominative case of the verb. Without -mak/-mek)

HE-SHE-IT -> Yapsın! (-sın/-sin/-sun/-sün)

WE -> We can not command ourselves.

YOU (PLURAL-FORMAL) -> Yapın! (-ın/-in/-un/-ün)

THEY -> Yapsınlar! (-sınlar/-sinler/-sunlar/-sünler)

If there is "a" or "ı" letter in latest syllable, we use;

He-she-it -> -sın

You -> -ın

They -> -sınlar

If there is "o" or "u" letter in latest syllable, we use;

He-she-it -> -sun

You -> -un

They -> -sunlar

If there is "e" or "i" letter in latest syllable, we use;

He-she-it -> -sin

You -> -in

They -> -sinler

If there is "ö" or "ü" letter in latest syllable, we use;

He-she-it -> -sün

You -> -ün

They -> -sünler

ANLAMAK -> TO UNDERSTAND 

Radical -> Anla (It is also command for "you" subject.)

Syllable -> An-la 

Latest syllable -> -la

We should use -> -sın/-ın/-sınlar

He-she-it -> Anlasın!

You -> Anlayın! ("y" is integration letter.)

They ->  Anlasınlar!

YAPMAK – TO DO                                BİLMEK – TO KNOW                  KOYMAK – TO PUT
GÖRMEK – TO SEE                               UZANMAK – TO LIE DOWN
UNUTMAK – TO FORGET                        UYUMAK – TO SLEEP
ANLAMAK – TO UNDERSTAND                 ÇÖZMEK – TO SOLVE 

NEGATIVE FORM:

When we want to make a sentence negative in imperative you should follow these steps: 

1. First you should remove infinitive. (-mek / -mak)

                 * Gitmek (Go) -> Git 
2. Secondly, you should add a privative. (-ma / -me) 

                 *Git + me 

That´s all. This negative form is for "you" subject. If you want to transform it for other subjects, you should add appendix from the table above. 

*Git + me -> Gitme (You)    Sen gitme!
*Git + me + sin -> Gitmesin (He-She-It)  O gitmesin!

ATTENTION!!

 If your imperative sentence is negative,  your appendixes have to be; 

For "He-She-It" -> -sın / -sin 
For "You (Plural)" -> -ın / -in
For "They" -> -sınlar / sinler 

So I mean; 

(+) Görmek -> Gör + sün -> Görsün (He-She-It)  O Görsün!
(-) Görmek -> Gör + me + sün    x It is wrong !!!

(-) Görmek -> Gör + me + sin -> Görmesin    O görmesin!    It is ture! 

You can use; 
 

For "He-She-It" -> -sın / -sin 
For "You (Plural)" -> -ın / -in
For "They" -> -sınlar / sinler    only! 

*(+) Oturmak (To sit) -> Otur -> Oturun -> (You / plural) 

*(-) Oturmak -> Otur -> Oturma -> Oturma + sın (You - plural) 

You should use privative regularly.

"-ma" is used if there is "a - ı - o - u" in last slyllable. 
"-me" is used if there is "e - i - ö - ü" in last slyllable.

* Uyumak (To sleep) -> Uyu + ma 

You should add "-ma" because there is "u" in last slyllable. 

*(+) Sormak (To ask) -> Sor / Sorsun / Sorsunlar
(-) Sormak -> Sorma / Sormasın / Sormasınlar

*(+) Yazmak (To write) -> Yaz / Yazsın / Yazsınlar
(-) Yazmak -> Yazma / Yazmasın / Yazmasınlar
