A lacuna ( lacunae or lacunas) is a gap in a manuscript, inscription, text, painting, or a musical work. A manuscript, text, or section suffering from gaps is said to be "lacunose" or "lacunulose". Some books intentionally add lacunas to be filled in by the owner (e.g., "The _____ played with the _____ in the _____."), often as a game or to encourage children to create their own stories.
