Questions & Answers about Onun boyu çok uzun.
What does onun mean here? Does it mean his or her?
Yes. Onun can mean his, her, or its, depending on context.
Turkish does not mark grammatical gender the way English does, so the same word is used for:
- his
- her
- its
In this sentence, onun is the possessor, so onun boyu means his/her height or his/her stature.
Why is it boyu and not just boy?
Because boyu includes a possessive suffix.
- boy = height, stature, length
- boyu = his/her/its height
In Turkish, possessed nouns usually take a possessive ending. So:
- onun boyu = his/her height
- literally: of him/her + height-his/hers
This is a very common Turkish structure:
- benim adım = my name
- senin evin = your house
- onun boyu = his/her height
So boyu is not a different dictionary word; it is boy with the 3rd person possessive ending.
Why is there no word for is in the sentence?
