Synecdoche

Synecdoche is using a part of something to refer to the whole thing (vice versa).

Eg. Referring a car to a set of 'wheels'

Eg. My car is broken (when it could just only be the engine).

Wheels are only a part of the car, but can be used to mean the entire car.

In my project, the painting is the synecdoche. The painting represents the imaginary world the boy has created in his mind. Every time he looks into the canvas, he is seeing his other reality.
