There's a good amount of death in The Cherry Orchard. It is mentioned over and over. The memory of a dead son and husband haunt the main character, Lubov. The clown threatens to kill himself. Departing family describe the house as "at the end of its life." And though Chekhov isn't explicit about it, we're pretty sure we witness the death of Fiers, the loyal old servant. Just like the shifting social landscape, death is an inevitable part of life.
Death is a shadow that drives Lubov to love.
The Cherry Orchard is about the death of a way of life.
