Questions & Answers about Çocuğun boyu hızla uzadı.
Because çocuğun means of the child or the child’s.
The ending -un / -ün / -ın / -in is the genitive ending, which marks possession.
- çocuk = child
- çocuğun = the child’s
There is also a sound change here:
- çocuk
- -un does not stay as çocukun
- it becomes çocuğun
This is a common Turkish sound change: final k often softens to ğ when a vowel-initial ending is added.
So in this sentence, çocuğun is the possessor: the child’s.
Because boyu is the possessed form: his/her/its height.
In Turkish, when one noun possesses another, the second noun usually also gets a possessive suffix.
So:
- boy = height, stature
- boyu = his/her/its height
Here the structure is:
- çocuğun boyu = the child’s height
This is a very common Turkish pattern:
- adamın arabası = the man’s car
- evin kapısı = the house’s door
- çocuğun boyu = the child’s height
So Turkish often marks possession on both nouns:
- the possessor gets the genitive
- the possessed noun gets a possessive suffix
