Turkish Language - the Necessitative Mood

Simple Tense of Obligation
I must go
I ought to go
I should go
I have to go
I have got to go

This Mood is formed by attaching the -li Suffix of Obligation to the short infinitive form of the verb. The suitable to be personal suffix is then added to denote the number of the person - I, you, he,we, you, they..

Expressing Obligation.

There are a number ways to express obligation in Turkish.
- The first way is to use the noun zor - trouble, difficulty, worry, problem,difficult, hard
zorunda kalmak [zor-u-nda = "in the problem"] - to be left no choice but (to do something)
zorunda olmak - to have to, be obliged to (do something)
- Or one can use an arabic word mecbur - necessity, need to..
mecbur olmak /-a/ {demands a Motion Towards Object) - to be forced to, be obliged to, have to (do something).
mecbur kalmak -/a/ {demands a Motion Towards Object) - to feel obliged to, feel that one has to (do something). (Bakmaya mecbur oldum.. - I felt (that) I had to look..)

These methods are widely used especially in notices and newspapers, but the verb itself has a Mood of Obligation which is explained below. There may be some fine differences in meaning and intent within these various methods of expressing obligation, but they can only be learned by experience and observation.

A full example with the verb - etmek - to do/to perform

In the table below we show all the meanings in English which the Turkish Necessitative replaces. We realize that the English method have slightly differing meanings which are better explained by a grammarian. Suffice it to say that these fine meaning are understood "in context" when speaking Turkish.

Obligation Mood - Formation

Example of an A-Dotted Verb bakmak - to see

The Short infinitive is formed by dropping the final -k from the Full Infinitive thus giving bakma for the Positive Verb stem while the Negative Verb Stem produces bakmama -(from bakamamak - not to see)
- Then with the addition of the undotted form of the-lı Suffix of Obligation we arrive at the necessitative mood verb roots bakmalı- for the Positive and bakmamalı- for the Negative..
- The verb form is completed by adding the personal endings of the verb "to be"

The Mood of Obligation - A-Undotted Verbs adds -malı- Suffix
bakmalıyımI ought to see/I must seebakmamalıyımI ought not to see
bakmalısınYou ought to see/You must seebakmamalısınYou ought not to see
O bakmalı(dır)He ought to see/He must seeO bakmamalı(dır)He ought not to see
bakmalıyızWe ought to see/we must seebakmamalıyızWe ought not to see
bakmalısınızYou ought to see/you must seebakmamalısınızYou ought not to see
bakmalı(dır)larThey ought to see/They must seebakmamalı(dır)larThey ought not to see

Example of an E-Dotted Verb girmek - to enter

Similarly for the E-Dotted Group of Verbs (where because of Vowel Harmony Rules the Suffix of Obligation takes its dotted form -li-) - girmek - to enter - will become girmeli- for the Positive and girmemeli- for the Negative..

The Mood of Obligation - E-Ddotted Verbs add -meli- Suffix
girmeliyimI ought to entergirmemeliyimI ought not to enter
girmelisinYou ought to entergirmemelisinYou ought not to enter
O girmeli(dir)He ought to enterO girmemeli(dir)He ought not to enter
