In Turkish, according to the grammatical structure two vowels can not come together. That’s why when we want to add a suffix which starts with a vowel, to a word which finishes with a vowel, we have to use buffer consonant.
In Turkish, there are two buffer consonants ; “y, n “
y is the main buffer consonant and most used one.
n buffer :
- is used if we want to add a suffix to the pronouns.
Bu + u --> Bu-n-u : bunu
O + a --> O-n-a : ona
- is used if we want to add a condition suffix ( -a –e – i – de –den) to the possesion suffix. Shortly it is used if we want to add a condition suffix to a noun phrase.
Fakirin evi-n-i satmışlar . ( They sold the house of the poor (one) )
Çocuğun kitabı-n-ı aldık. ( We bought the book of the child)
Ağrı Dağı-n-ı göreceğim ( I will visit Ağrı mountain)
- is used if we want to add a suffix to make a noun phrase.
Ali - n – in kalemi à Ali’nin kalemi ( Ali’s pencil)
Kasaba-n-ın sıcağı ( the hot weather of the town)
For all situations except given above, - y buffer will be used.
Kedi+y+i getir --> Kediyi getir. ( Bring the cat.)
Silgi+y+i kaybettim. --> Silgiyi kaybettim. ( I have lost the eraser.)
