A play is a form of theatre that primarily consists of script between speakers and is intended for acting rather than mere reading. The writer and author of a play is known as a playwright.

Plays are staged at various levels, ranging from London's West End and New York City's Broadway – the highest echelons of commercial theatre in the English-speaking world – to regional theatre, community theatre, and academic productions at universities and schools.

A stage play is specifically crafted for performance on stage, distinct from works meant for broadcast or cinematic adaptation. They are presented on a stage before a live audience. Some dramatists, notably George Bernard Shaw, have shown little preference for whether their plays are performed or read. The term "play" encompasses the written texts of playwrights and their complete theatrical renditions.

Comedies are plays designed to elicit humor and often feature witty dialogue, eccentric characters, and unusual situations. Comedies cater to diverse age groups. Comedies were one of the original two genres of Ancient Greek drama, the other being tragedies. Examples of comedies include William Shakespeare's A Midsummer Night's Dream, and in the modern day, The Book of Mormon.

Farces constitute a nonsensical subgenre of comedy that frequently involve humour. They often rely on exaggerated situations and slapstick comedy. An example of a farce is William Shakespeare's play The Comedy of Errors, or Mark Twain's work Is He Dead?.

Satirical plays provide a comic perspective on contemporary events while also making political or social commentary, often highlighting issues such as corruption. Examples of satirical plays are Nikolai Gogol's The Government Inspector and Aristophanes' Lysistrata. Satire plays are a distinct and popular form of comedy, often considered a separate genre in themselves.

Restoration comedy is a genre that explores relationships between men and women, often delving into risqué themes for its time. The characters in restoration comedies frequently embody various stereotypes, contributing to the genre's consistent themes. This similarity also led to a homogeneity of message and content across most plays in this genre. Despite this, restoration comedy's exploration of unspoken aspects of relationships fostered a more intimate connection between the audience and the performance.

Restoration comedy's origins are rooted in Molière's theories of comedy, although they differ in tone and intention. The misalignment between the genre's morals and the prevailing ethics of its era is a point of interest when studying restoration comedy. This dissonance might explain why, despite its initial success, restoration comedy did not endure through the 17th century. Nonetheless, contemporary theatre theorists have been increasingly intrigued by restoration comedy as they explore performance styles with unique conventions.
