The imperative mood (abbreviated IMP) expresses commands or requests as a grammatical mood. These commands or requests urge the audience to act a certain way. It also may signal a prohibition, permission, or any other kind of exhortation.

Formulation of the English imperative simply uses the bare infinitive form of the verb. The infinitive form usually corresponds to the second-person present indicative form, with the exception of the verb be. The subject of these sentences is usually understood as you (the second person) except in the case of "Let's" which implies first person and at least a second person. Other languages such as Latin, French and German have several inflected imperative forms, which can vary according to grammatical categories such as:

For instance, Latin regular forms can exist:

Some consider this richness of forms useful for a better understanding, particularly because no subject pronoun normally specifies with the imperative.

The use of the imperative mood be seen as impolite, inappropriate or even offensive in certain circumstances. Commonly, polite speech will instead express the same thing as a question or statement, such as:

Sir Charles Spencer "Charlie" Chaplin, KBE (16 April 1889 – 25 December 1977) was an English comic actor, film director and composer best known for his work during the silent film era. He became the most famous film star in the world before the end of World War I. Chaplin used mime, slapstick and other visual comedy routines, and continued well into the era of the talkies, though his films decreased in frequency from the end of the 1920s. His most famous role was that of The Tramp, which he first played in the Keystone comedy Kid Auto Races at Venice in 1914. From the April 1914 one-reeler Twenty Minutes of Love onwards he was writing and directing most of his films, by 1916 he was also producing them, and from 1918 he was even composing the music for them. With Mary Pickford, Douglas Fairbanks and D. W. Griffith, he co-founded United Artists in 1919.

Chaplin was one of the most creative and influential personalities of the silent-film era. He was influenced by his predecessor, the French silent film comedian Max Linder, to whom he dedicated one of his films. His working life in entertainment spanned over 75 years, from the Victorian stage and the music hall in the United Kingdom as a child performer, until close to his death at the age of 88. His high-profile public and private life encompassed both adulation and controversy. Chaplin was identified with left-wing politics during the McCarthy era and he was ultimately forced to resettle in Europe from 1952.
