What does outliner mean?
An outliner is someone who creates the basic structure of a proposed or existing work before that work is fully developed. In publishing, education, and research, this may mean preparing a concise sequence of headings or main points for an article, chapter, speech, or report. In design and technical contexts, an outliner may instead be a tool used to trace the boundary of an object or create an external contour. The word is related to the familiar noun “outline,” meaning either a preliminary account of a work’s organization or the external boundary of a shape. Although an outline is the result, an outliner is the person or instrument responsible for producing it. The term is not especially common, but it is useful in editorial and creative work whenever the essential task is to establish structure, emphasis, or boundaries before the more detailed phase begins.
A person who prepares an outline or presents the main points and organization of a proposed work.

Where does outliner come from?
The word “outliner” was formed in English by combining “outline” with the agent suffix “-er,” a pattern meaning a person or device that performs an action. “Outline” itself combines “out” with “line,” referring originally to drawing the exterior boundary of a form and later extended to a preliminary statement of the main points in a text. Several English words, including “underline” and “delineate,” belong to the same broader line-related vocabulary, with “delineate” continuing the Latin root linea, “line.”
