does this help at all i found a file

n this example we used gerekmek in (i)yor-present tense. gerekmek always is put into the 3rd person singular, as it refers to the “doing” itself, not to the person who acts. You can combine also in the other so far known tenses.

Examples:
PAST: Dün akşam eve gitmem gerekti. = Yesterday evening I had to go home..

FUTURE: Yarın havalimanına gitmem gerekecek. = Tomorrow I’m going to have to go to the airport..

İR-PRESENT: Her gün okula gitmem gerek. = Everyday I have to go to school.

Maybe you ask now “where is the ir-suffix?". It’s not necessary as in this present tense the verb stem of gerekmek is sufficient to express the need.

Actually you could also blank out the other tense suffixes as the words dün and yarın already indicate when the actions take place.

10.1.6 Negation of "gerekmek"

For negating gerekmek you need the additional suffix -m(e), in infinitive form: gerekmemek.

Examples:
Gitmesi gerekmiyor. = He/she/it hasn’t to go.
Dün eve gitmem gerekmedi. = Yesterday I hadn’t to go home.
Yarın havalimanına gitmen gerekmeyecek. = Tomorrow you’re not going to have to go to the airport.

Very clear information. Thank you, acute.

Actually you can´t blank out past tense suffix even you use "dün". Because "gerek" without a tense suffix only express present and future. So you should use past tense suffix after gerek when the action occured in the past.

Ex: Dün akşam eve gitmem gerekti.

Does gerekmek function as a normal verb in inlayed sentences? I tried some equivalents of relative clauses to test the principle  -  they may be incorrect.

the flowers which I had to buy almam gerektiği çiçekler

the traveller who had to open her bag torbasını açması gereken yolcu

the father whose daughter had to marry the butcher kızının kasapla evlenmesi gerekmiş baba

miş makes the verb gerek adjective here. And "gerek" is the predicate of inlayed sentence.

Posted twice.

Strange...I need to think about this again.

Gitmem gerektiği zaman söyle. Tell me when I have to go.

Bitirmem gereken ödevlerim var. I have homeworks that I have to finish.

Söylemem gerekecek şey onu üzebilir. The thing I will have to say can make him upset.

We don´t use gerekir as an adjective.

Thanks, gokuyum. It was a bad question but a good answer. Some way which I don´t understand yet I see the main clause object where I expect to see the subject. I will have to stare at your examples for some while.

When something sounds weird there must be a reason for it. (I don´t need the reason but it is just interesting.)
