A very common, almost defining feature of satire is its strong vein of irony or sarcasm, but parody, burlesque, exaggeration, juxtaposition, comparison, analogy, and double entendre are all frequently used in satirical speech and writing. The essential point, however, is that "in satire, irony is militant". This "militant irony" (or sarcasm) often professes to approve the very things the satirist actually wishes to attack.

Term

The word satire comes from Latin satura lanx and means "medley, dish of colourful fruits" - it was held by Quintilian to be a "wholly Roman phenomenon" (satura tota nostra est). This derivation properly has nothing to do with the Greek mythological figure satyr. To Quintilian, the satire was a strict literary form, but the term soon escaped from its original narrow definition. Robert Elliott wrote:

"As soon as a noun enters the domain of metaphor, as one modern scholar has pointed out, it clamours for extension; and satura (which had had no verbal, adverbial, or adjectival forms) was immediately broadened by appropriation from the Greek word for “satyr” (satyros) and its derivatives. The odd result is that the English “satire” comes from the Latin satura; but “satirize,” “satiric,” etc., are of Greek origin. By about the 4th century AD the writer of satires came to be known as satyricus; St. Jerome, for example, was called by one of his enemies 'a satirist in prose' ('satyricus scriptor in prosa'). Subsequent orthographic modifications obscured the Latin origin of the word satire: satura becomes satyra, and in England, by the 16th century, it was written 'satyre.'"

Satire (in the modern sense of the word) is found in many artistic forms of expression, including literature, plays, commentary, and media such as song lyrics.

The term is also today applied to many works other than those which would have been considered satire by Quintilian - including, for instance, ancient Greek authors predating the first Roman satires. Public opinion in the Athenian democracy, for example, was remarkably influenced by the political satire written by such comic poets as Aristophanes for the theatre.

Satire and humour

Satirical works often contain "straight" (non-satirical) humour - usually to give some relief from what might otherwise be relentless "preaching". This has always been the case, although it is probably more marked in modern satire. On the other hand some satire has little or no humour at all. It is not "funny" - nor is it meant to be.

Humour about a particular subject (politics, religion and art for instance) is not necessarily satirical because the subject itself is often a subject of satire. Nor is humour using the great satiric tools of irony, parody, or burlesque always meant in a satirical sense.
