zakoczeniu
Zakoczeniu is not a recognized entry in standard Polish lexicons. It appears to be a misspelling or typographical error for zakończeniu, the locative form of the noun zakończenie, which means end, conclusion, or finishing of a process, event, or text. The word zakończenie derives from the verb zakończyć (to finish, to complete). The locative zakończeniu is used with prepositions such as na or w to refer to the ending phase of something.
In practice, zakończenie denotes the final part or conclusion of a thing, for example: na zakończeniu konferencji
Because zakoczeniu does not exist as an independent lemma in major Polish dictionaries, it should be treated
The term is related to other forms built from the same root, including zakończony (finished) and zakończyć
