Genre (/ˈʒɒnrə/ or /ˈdʒɒnrə/; from French, genre French pronunciation: [ʒɑ̃ʁ], "kind" or "sort", from Latin: genus (stem gener-), Greek: genos, γένος) is the term for any category of literature or other forms of art or entertainment, e.g. music, whether written or spoken, audial or visual, based on some set of stylistic criteria. Genres are formed by conventions that change over time as new genres are invented and the use of old ones are discontinued. Often, works fit into multiple genres by way of borrowing and recombining these conventions. Genre theory is a branch of critical theory.

Hyperbole (/haɪˈpɜrbəliː/ hy-pur-bə-lee;^[1] Greek: ὑπερβολή hyperbolē, "exaggeration") is the use of exaggeration as a rhetorical device or figure of speech. It may be used to evoke strong feelings or to create a strong impression, but is not meant to be taken literally.^[2]

Iambic pentameter (from Greek: ἰαμβικός πεντάμετρος, iambikos pentametros, meaning to have five iambs) is a commonly used metrical line in traditional verse and verse drama. The term describes the particular rhythm that the words establish in that line. That rhythm is measured in small groups of syllables; these small groups of syllables are called "feet". The word "iambic" describes the type of foot that is used (in English, an unstressed syllable followed by a stressed syllable). The word "pentameter" indicates that a line has five of these "feet."

An idiom (Latin: idioma, "special property", f. Greek: ἰδίωμα – idiōma, "special feature, special phrasing", f. Greek: ἴδιος – idios, "one’s own") is a combination of words that has a figurative meaning, due to its common usage. An idiom's figurative meaning is separate from the literal meaning ordefinition of the words of which it is made.^[1] Idioms are numerous and they occur frequently in all languages. There are estimated to be at least 25,000 idiomatic expressions in the English language.^[2]

An image (from Latin: imago) is an artifact that depicts or records visual perception, for example a two-dimensional picture, that has a similar appearance to some subject – usually a physical object or a person, thus providing a depiction of it.

Imagery, in a literary text, is an author's use of vivid and descriptive language to add depth to their work. It appeals to human senses to deepen the reader's understanding of the work.

Inform is a programming language and design system for interactive fiction originally created in 1993 by Graham Nelson. Inform can generate programs designed for the Z-code or Glulx virtual machines. Versions 1 through 5 were released between 1993 and 1996. Around 1996, Nelson rewrote Inform from first principles to create version 6 (or Inform 6).^[2] Over the following decade, version 6 became reasonably stable and a popular language for writing interactive fiction. In 2006, Nelson released Inform 7 (briefly known asNatural Inform), a completely new language based on principles of natural language and a new set of tools based around a book-publishing metaphor.

Internal monologue, also known as inner voice, internal speech, or verbal stream of consciousness is thinking in words. It also refers to the semi-constant internalmonologue one has with oneself at a conscious or semi-conscious level.

In literature, internal conflict is the struggle occurring within a character's mind. As opposed to external conflict, in which a character is grappling some force outside of him or herself, the dilemma posed by an internal conflict is usually some ethical or emotional question. Indicators of internal conflict would be a character's hesitation or self-posing questions like "what was it I did wrong?".^[1]

In poetry, internal rhyme, or middle rhyme, is rhyme that occurs within a single line of verse.^[1]

Irony (from the Ancient Greek εἰρωνεία eirōneía, meaning dissimulation or feigned ignorance),^[1] in its broadest sense, is a rhetorical device,literary technique, or event characterized by an incongruity, or contrast, between reality (what is) and appearance (what seems to be). The term may be further defined into several categories, among which are: verbal, dramatic, and situational.

Juxtaposition is the act or placement of two things (usually abstract concepts) near each other.
