A haiku presents an event.
A typical structure, as described by R. H. Blyth in his fundamental work, can be described as follows:
| Environment;
Subject Action. |
Circumstances
One begins by setting the stage. A few words will do. They describe the circumstances, generally with a reference to the season .
Exposition generally places in the first line. It ends with a semicolon, thus creating a pause to give the reader time to set the stage.
The body proper
This second part contains the subject of the haiku and the action.
The subject is the theme of the haiku.
The action
The action is what happens. That is what brings life to the haiku. Without that action, the haiku is only a photography.
