comedy

n. amusing play, funny drama

In common, present day usage the word comedy almost always refers to the creation or presentation of humor with the intention of provoking laughter. Most comedy contains variations on the elements of surprise, incongruity, conflict, repetitiveness, and the effect of opposite expectations, but there are many recognized genres of comedy.  Satire and political satire use ironic comedy to portray persons or social institutions as ridiculous or corrupt, thus alienating their audience from the object of humor. Parody borrows the form of some popular genre, artwork, or text but uses certain ironic changes to critique that form from within (though not necessarily in a condemning way). Screwball comedy derives its humor largely from bizarre, surprising (and improbable) situations or characters. Black comedy is defined by dark humor that makes light of so called dark or evil elements in human nature. Similarly scatological humor, sexual humor, and race humor create comedy by violating social conventions or taboos in comedic ways. A comedy of manners typically takes as its subject a particular part of society (usually upper class society) and uses humor to parody or satirize the behavior and mannerisms of its members. Romantic comedy is a popular genre that depicts burgeoning romance in humorous terms and focuses on the foibles of those falling in love.
