Questions & Answers about O bunu iddia etti.
Yes. O is a third-person singular pronoun and does not mark gender, so it can mean he, she, or it, depending on context.
Also, in other contexts o can mean that, but in this sentence it is functioning as the subject pronoun.
That is true: Turkish often leaves out subject pronouns when the subject is clear from context.
So O bunu iddia etti could often be shortened to Bunu iddia etti.
Including o can add:
- clarity: to make the subject explicit
- contrast: He/She claimed this, not someone else
- emphasis: drawing attention to who made the claim
This is especially useful because etti by itself does not tell you gender, and third-person singular has no special ending that identifies the subject as clearly as some other persons do.
