"Fictionary" is a word that refers to a made-up, imaginary or fictitious thing. It is spelled with the prefix "fic-" meaning fiction, and the suffix "-tionary" meaning a collection of words or a dictionary. The correct spelling is [fik-shuh-ner-ee] /ˈfɪkʃəˌnɛri/ with the stress on the second syllable. The word is commonly used in games and storytelling contexts where players or writers may create their own words or concepts to enhance the narrative.
The word "fictionary" comes from a combination of the words "fiction" and "dictionary". It is a playful blend of these two words to create a term specifically referring to a dictionary of made-up or invented words, often used in games such as charades or Pictionary. The exact origins of the word are difficult to trace, as it appears to be a fairly recent and informal coinage.
