The main difference between Satire and Sarcasm is that the Satire is a genre of arts and literature in the form of humor or ridicule and Sarcasm is a sharp, bitter, or cutting expression or remark; a bitter gibe or taunt
In fiction and less frequently in non-fiction, satire is a genre of literature and performing arts, in which vices, follies, abuses and shortcomings are held up to ridicule, ideally with the intent of shaming individuals, corporations, government, or society itself into improvement. Although satire is usually meant to be humorous, its greater purpose is often constructive social criticism, using wit to draw attention to both particular and wider issues in society.
A feature of satire is strong irony or sarcasm—”in satire, irony is militant”—but parody, burlesque, exaggeration, juxtaposition, comparison, analogy, and double entendre are all frequently used in satirical speech and writing. This “militant” irony or sarcasm often professes to approve of (or at least accept as natural) the very things the satirist wishes to question.
Satire is nowadays found in many artistic forms of expression, including internet memes, literature, plays, commentary, television shows, and media such as lyrics.
Sarcasm is “a sharp, bitter, or cutting expression or remark; a bitter gibe or taunt”. Sarcasm may employ ambivalence, although sarcasm is not necessarily ironic. Most noticeable in spoken word, sarcasm is mainly distinguished by the inflection with which it is spoken and is largely context-dependent.
