Questions & Answers about O, kaba biri değil; tam tersine çok kibar ve duyarlı.
O is a third-person pronoun in Turkish. Depending on context, it can mean he, she, or it.
In this sentence, because the rest of the sentence describes a person, O most naturally means he or she.
Turkish does not normally mark gender in pronouns, so you need context to know which one is meant.
In Turkish, the verb to be is often not expressed in simple present-tense sentences.
So:
- O kibar. = He/She is polite.
- O duyarlı. = He/She is sensitive/considerate.
In the negative, however, Turkish usually uses değil:
- O kaba değil. = He/She is not rude.
So the sentence does contain the idea of is, but Turkish handles it differently from English.
