Etymology

The word "directory" originates from the Late Latin directorium, meaning "a guide or set of instructions," derived from directus (past participle of dirigere, "to guide or align"). The morpheme direct retains its core meaning of "straight" or "to guide," while -ory (from Latin -orium) denotes a place or collection. Over time, "directory" evolved to refer to systematic lists (e.g., telephone directories) and later to digital folders in computing, reflecting its function as an organized guide.
