To adapt a screenplay means to transform or modify it in order to make it suitable for another medium, such as a book, play, radio drama, television show, or film. This process involves reworking and reshaping the original story so that it can be effectively told through a different format while maintaining its core themes, characters, and plot points. Adaptation often requires creative interpretation, omission of certain details, addition of new elements, and adjustments to dialogue or narrative structure in order to make it work within the constraints and conventions of the new medium.
