Haplology

In Turkey Turkish, haplology can be seen;

1-     In some disyllables, if a suffix which starts with a vowel is added.

Ağız + ı – Ağzı  (Ağızı is wrong)

Alın + ı – Alnı ( Alını is wrong)

Bağır + ı – Bağrı (Bağırı is wrong)

Beniz + i – Benzi

Beyin + imiz – Beynimiz

Boyun + u – Boynu

Böğür + üm – Böğrüm

Gönül + ün – Gönlün

Karın + ım – Karnım

Sabır + ım –Sabrım

Nesil + i – Nesli

There is no exact rule for this. But you may understand that the aim is making pronunciation easier, if you pronounce right and wrong usage in succession.

2-   In some combined words.

Pazar ertesi – Pazar+ertesi – Pazartesi

Kayın ana – Kayın+ana – Kaynana

Ne için – Ne+için – Niçin

Ne asıl – Ne+asıl – Nasıl

Important Note :

Eventhough in colloquial Turkish, haplology seen in the words given below, in written language it is wrong to write them withouth vowel.  ( As it will be seen, it doesn’t obey the rule given above. The word finishes with vowel  not the suffix starts with vowel.)

içeri – içeri + de – içeride

içeri – içeri + de – içerde ( it is right in daily speech, but in written language it is wrong)

şura – şura + da – şurada

şura – şura + da – şurda ( it is right in daily speech, but in written language it is wrong)

bura – bura + da – burada

bura – bura + da – burda

Other words which can be counted in this group are ; ora, yukarı, aşağı ileri etc.
