What is the difference between each one of those?

Does it have a degree of necessity as in English ?
There is difference in degree between
Must ,have to, may, might,ought to

İf not,so what is the difference between those structures ?

eylem + mA + iyelik eki [gerek/lazım ][gerek- +zaman eki]


eylem + mAk [gerek/lazım ][gerek- +zaman eki]

[zorunda + (y) kişi eki]
[mecburiyetinde + (y) kişi eki ]


eylem + mAk [zorunda kal- +zaman eki +kişi eki]
eylem + mAyA [ mecbur + kişi eki ]


And zaman eki .... like what ? is it sort of zaman suffix,or what ?

Tşk ederim

Have to = -mek zorunda olmak, -mek mecburiyetinde olmak, -meye mecbur olmak

Literally though
-mek zorunda olmak = to be forced to ...
-mek mecburiyetinde olmak = to be obliged to ...

You can use -meli/-malı for anything at the beginning.
I must go = Gitmeliyim
I have to go = Gitmeliyim
I should go = Gitmeliyim

Then when you feel comfortable
I have to go = Gitmek zorundayım

Other forms like
Gitmek mecburiyetindeyim or
Gitmeye mecburum
are not preferred though they are possible. Forget them at the beginning.

Ohh, Tşk ederim,

Ama, what is zaman eki ?

Can you give some examples ?

gitmek zorunda kal-dı-m (verb+zaman eki+kişi eki) a past tense example
gitmek zorunda kal-dı-n
gitmek zorunda kal-ı-r-ım a present tense example

Anladım, Çok TŞK leamues

ok,now i have to make some ödev about the above ,and i need to know where to use each form of those,and on what base ?

eylem + mA + iyelik eki [gerek/lazım ][gerek- +zaman eki]


eylem + mAk [gerek/lazım ][gerek- +zaman eki]

[zorunda + (y) kişi eki]
[mecburiyetinde + (y) kişi eki ]


eylem + mAk [zorunda kal- +zaman eki +kişi eki]
eylem + mAyA [ mecbur + kişi eki ]

Tşkler

These formuluzations need some examples:

1. eylem + mA + iyelik eki [gerek/lazım ][gerek- +zaman eki]
1. gitmem gerek / gitmem gerekiyor : I need to go
-m in gitmem is possessive suffix. In first case it is just gerek as it is and in second case there ,s a tense suffix -iyor in gerekiyor.
-------------
2. eylem + mAk [gerek/lazım ][gerek- +zaman eki]
2. gitmek gerek / gitmek gerekiyor : it is necessary to go
-------------
3. [zorunda + (y) kişi eki]
4. [mecburiyetinde + (y) kişi eki ]
These are the continuation of previous section. It should be like this:

3. eylem + mAk [zorunda + (y) kişi eki]
4. eylem + mAk [mecburiyetinde + (y) kişi eki ]

3. gitmek zorundayım : I must go

4. gitmek mecburiyetindeyim : I must go
--------------
5. eylem + mAk [zorunda kal- +zaman eki +kişi eki]
6. eylem + mAyA [ mecbur + kişi eki ]

5. gitmek zorunda kaldım : I had no other choice than going

6. gitmeye mecburum : I must go

Çok Tşk Erdinç,

Anladım,appreciated

Ok,and when i want to put it into nagative,

İ mean,to say,i shouldn't or Must not..ect

İt is eylem,so we should use the (me,ma) suffix as usual, right ?

But i found this örnek,

Misafirler akşam gelecek,evi sabahtan toplamak zorunda değilim

Why said 'değilim' here,and not toplaMAmak ?

And this goes for all the other cases too ?

gitmek zorundayım: I have to go
The obligatory is the activity: "to go"

gitmemek zorundayım: I must not go
The obligatory is the activity: "not to go" (="to stay")

gitmek zorunda değilim: I don't have to go
There is no obligatory: "I may go or I may not go"

so:
toplamak zorunda değilim: no obligatory.
toplamamak zorundayım: obligatory is "not to do"

what is değilim then ?

Why did they use it here ?

Misafirler akşam gelecek,evi sabahtan toplamak zorunda değilim

What's the difference between "gerek", "gerekir" and gerekiyor" as the one can be used instead of an other?

Bu konuyu Ahmet Bey'le konuşmanız gerek.
Bu konuyu Ahmet Bey'le konuşmanız gerekir.
Bu konuyu Ahmet Bey'le konuşmanız gerekiyor.

Any difference between three?

Selam herkesecan someone help me T-E

canim bende seni olecek kadar seviyorum herinsan hayal kurar.


also i want to know what the meaning of çitirim ?
thank you

gitmek zorundayım: I have to go
The obligatory is the activity: "to go"

gitmemek zorundayım: I must not go
The obligatory is the activity: "not to go" (="to stay")

gitmek zorunda değilim: I don't have to go
There is no obligatory: "I may go or I may not go"

so:
toplamak zorunda değilim: no obligatory.
toplamamak zorundayım: obligatory is "not to do"


gitmak zorundayım=I have to go
gitmek zorunda değil=I dont have to go
gitmeliyim=I must go
gitmemeliyim=I must not go


Note=must and have to dont have the same degree
must and have to dont have the same meaning

Yes,i know they are not same degree,but note here
There are more than one form with the same meaning,so what is the difference in usage between them ?

Instead of “zorunda” or "mecburiyetinde" + “to be” personal endings, “zorunda” or "mecburiyetinde"+ “kalmak” can be used. The difference between two is that both expresses obligation but the former expresses an obligation imposed by the speaker while the latter expresses an external obligation, i.e. one imposed by external authority or circumstances:

Odanı temizlemek zorundasın (mecburiyetindesin). (obligation imposed by the speaker)

9:00 trenini kaçrıdığım için 9:15 trenini beklemek zorunda (mecburiyetinde) kaldım. (the obligation imposed by the the circumstance)

Askerde saçlarını kısa kestirmek zorunda kalacaksın. (the army will oblige you to do that).

There is no difference between "zorunda" and "mecburiyetinde". The latter is Arabic origin.

What would be your explanation then?

Who might be the speaker other than a mother?

Wouldn't the sister say in that case that "Annem odanı temizlemen gerektiğini / temizlemeni söyledi."

And also is an obligation necessarily imposed by a speaker who is older than the person whom he addresses?

I dont see sth wrong or the otherwise, just discussing to get the correct use.

Ok then,here is 2 group of obligations

1.zorunda,mecburiyetinde.
And
2.zorunda kal,mecbur.

zorunda,mecburiyetinde,they are same in usage
And zorunda kal,mecbur are same in usage too,right?

What is the difference in usage between the 2 groups ?

one is forced by others,or circumstances,and the other are forced by myself,or what ???

By the way, zorunda kalmak refers on "become", "the change of the conditionals"

Gitmek zorundaydım: I had to go
Gitmek zorunda kaldım: The conditionals changed, so I had to go/ I became in the obligatory to go

well,it was just written in my book in 2 groups,so i thought there must be some difference between them

Like there is a difference between gerek,lazı,malı and zorunda,mecbur

Thats all

Thx caliptrix, you are really helpful

Please, correct me if I am wrong, but I think ´mecbur´ is used mostly as a formal word, and ´zorunda´ is used both as a formal (unified) and colloquial word.

And also, aren´t ´gerek´ and ´lazim´ are used mostly to indicate necessity rather than obligation?

A nice thread you found from the history, sufee.

What do you mean by obligation, what do you mean by necessity? I think necessity is a superordinate term which covers

1. a must caused by the actor´s own qualities or circumstances

2. a must caused by an authority

3. certainty.

Of course natives will find nuances in the meanings but I think there is a very clever note earlier in this thread:

I am afraid my division 1-3 doesn´t exist in any language. It exists in modal logics only. Natural languages mix the groups together, for instance I have been taught -meli expresses all three kinds of necessity and it doesn´t cause any kind of confusion.
