What do you understand by the stage directions that say there are no sets?

Stage directions that indicate "no sets" mean that the play should be performed without the use of traditional stage scenery or props. This can be done for a variety of reasons, such as to:

* Create a more minimalist or abstract production

* Focus the audience's attention on the actors and their performances

* Allow the audience to use their imaginations to create the setting

* Save money on production costs

Some famous examples of plays that have been performed without sets include:

* Samuel Beckett's "Waiting for Godot"

* Edward Albee's "Who's Afraid of Virginia Woolf?"

* Caryl Churchill's "Cloud 9"
