Subtext or undertone is any content of a creative work which is not announced explicitly by the characters or author, but is implicit or becomes something understood by the observer of the work as the production unfolds. Subtext can also refer to the thoughts and motives of the characters which are only covered in an aside. Subtext can also be used to imply controversial subjects without specifically alienating people from the fiction, often through use of metaphor. Especially in light of their inherently ambiguous and self-referential character, many authors have explicitly used subtexts (or subtexts about subtexts) in humor.
Subtext is content underneath the dialogue. Under dialogue, there can be conflict, anger, competition, pride, showing off, or other implicit ideas and emotions. Subtext is the unspoken thoughts and motives of characters — what they really think and believe.
Subtext is also a frequently used method of subtly inserting social or political commentary into fiction. Subtext is often also inserted in narratives where explicit themes are unable to be shown or expressed due to censorship or simply interest in appealing to a general audience. Frequently , these subtexts may include a sexual nature or possible references to sexual orientation. Their inclusion is such so that they are easily overlooked by younger viewers but may be caught by more mature viewers. Subtext also serves to add complexity to a premise that may superficially appeal to younger viewers but may also attract older fans, as is often the case with cartoons, science fiction and fantasy. It also may serve to aid in suspension of disbelief.
Subtext includes information about the period and culture in which the author of a book is writing that may not be deliberately articulated but is conveyed through the text in speech, social customs or historical details.
A more recently coined term, metamessage (also spelled as meta-message and meta message) is considered by some authors to be synonymous with subtext.Metamessage is a term more commonly used in the analysis of business communication rather than of literary works.
The author David Baboulene, in his practical academic work on story theory, The Story Book, defines subtext as "the result of any form of gap in knowledge between any of the participants in a story; for example, between the author and a character, between two characters or between the audience and at least one character."
