This is the 2119th most frequent Turkish word.
başkanına
"To your president" or "to your chairperson."
In this sentence, 'başkanına' is the dative form of 'başkan' (president), indicating the recipient of the action (to their president).
Başkanına yeni bir rapor sundular.
They presented a new report to their president.
Here, 'başkanına' refers to the leader (başkan) of the team (ekibin), again showing the dative case used for the indirect object of the verb (the person receiving the award).
Ekibin başkanına bir ödül verildi.
An award was given to the leader of the team.
In this sentence, 'başkanına' is part of the possessive structure (the president of the party) and demonstrates the dative case indicating the object of admiration.
