Alternate history or alternative history is a genre of fiction consisting of stories that are set in worlds in which history has diverged from the... actual history of the world. It can be variously seen as a sub-genre of literary fiction, science fiction, and historical fiction; different alternate history works may use tropes from any or all of these genres. It is sometimes abbreviated AH. Another occasionally used term for the genre is "allohistory" . Since the 1950s, this type of fiction has to a large extent merged with science fictional tropes involving cross-time travel between alternate histories or psychic awareness of the existence of "our" universe by the people in another; or ordinary voyaging uptime or downtime that results in history splitting into two or more time-lines. Cross-time, time-splitting and alternate history themes have become so closely interwoven that it is impossible to discuss them fully apart from one another.

Science fiction is a genre of fiction dealing with imaginary but more or less plausible content such as future settings, futuristic science and... technology, space travel, aliens, and paranormal abilities. Exploring the consequences of scientific innovations is one purpose of science fiction, making it a "literature of ideas". Science fiction is largely based on writing rationally about alternative possible worlds or futures. It is similar to, but differs from fantasy in that, within the context of the story, its imaginary elements are largely possible within scientifically established or scientifically postulated laws of nature . The settings for science fiction are often contrary to known reality, but most science fiction relies on a considerable degree of suspension of disbelief, which is facilitated in the reader's mind by potential scientific explanations or solutions to various fictional elements. Science fiction elements include: Science fiction is difficult to define, as it includes a wide range of subgenres and themes.

Satire is primarily a literary genre or form, although in practice it can also be found in the graphic and performing arts. In satire, vices,... follies, abuses, and shortcomings are held up to ridicule, ideally with the intent of shaming individuals, and society itself, into improvement. Although satire is usually meant to be funny, its greater purpose is often constructive social criticism, using wit as a weapon. A common 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 the very things the satirist wishes to attack. Satire is nowadays found in many artistic forms of expression, including literature, plays, commentary, and media such as lyrics. The word satire comes from the Latin word satur and the subsequent phrase lanx satura. Satur meant "full," but the juxtaposition with lanx shifted the meaning to "miscellany or medley": the expression lanx satura literally means "a full dish of various kinds of fruits.

Humour or humor is the tendency of particular cognitive experiences to provoke laughter and provide amusement. The term derives from the humoral... medicine of the ancient Greeks, which taught that the balance of fluids in the human body, known as humors , control human health and emotion. People of all ages and cultures respond to humour. The majority of people are able to experience humour, i.e., to be amused, to laugh or smile at something funny, and thus they are considered to have a sense of humour. The hypothetical person lacking a sense of humour would likely find the behaviour induced by humour to be inexplicable, strange, or even irrational. Though ultimately decided by personal taste, the extent to which a person will find something humorous depends upon a host of variables, including geographical location, culture, maturity, level of education, intelligence and context. For example, young children may favour slapstick, such as Punch and Judy puppet shows or cartoons such as Tom and Jerry. Satire may rely more on understanding the target of the humour and thus tends to appeal to more mature audiences.
