1. To preserve or retain the conclusion or final part of something, such as a story, movie, or plan
We decided to keep the ending of the original book instead of changing it for the film adaptation.
Decidimos manter o final do livro original em vez de alterá-lo para a adaptação do filme.
2. To not reveal or spoil the conclusion of a narrative
Please keep the ending secret; I haven't watched the movie yet.
Por favor, mantenha o final em segredo; ainda não assisti ao filme.
