The Language of Drama

just something to be heard or read, but is performed

before an audience.

is seen in remarks and stage directions
the action is fragmented

into act and scenes
the use of both prose and poetry
the language is always stylized, i.e. it strives to retain the modus of literary English, unless the playwright has a particular aim, which requires the use of non-literary forms and expressions

personae, and time and place are established. We learn about

the antecedents of the story. Attention is directed toward the germ of conflict and dramatic tensions.
Act 2 – Complications. The course of action becomes more complicated, the "tying of knots" takes place. Interests clash, intrigues are spawned, events accelerate in a definite direction. Tension mounts, and momentum builds up.
Act 3 – The Climax of Action. The development of conflict reaches its high point, the Hero stands at the crossroads, leading to victory or defeat, crashing or soaring.
Act 4 – Falling Action. Reversals. The consequences of Act 3 play out, momentum slows, and tension is heightened by false hopes/fears. If it's a tragedy, it looks like the Hero can be saved. If not, then it looks like all may be lost.
Act 5 – Catastrophe. The conflict is resolved, whether through a catastrophe, the downfall of the hero, or through his victory and transfiguration.
