Etymology: The word began as a medieval guide rather than a list of names. Middle English "directorie" came from Medieval Latin "dīrēctōrium", a book of instructions showing how to perform rites or services, the sense that still survives in the ecclesiastical "directory" of prayers. The Latin base "dīrēctus" means "straight" or "directed", so the idea was a book that pointed you the right way. The sense of a register of names and addresses is much later and is a semantic development, not a separate root. A book that laid out how to find people or services, arranged in order, gradually came to mean the listing itself, and a telephone or street directory is simply a guide to where things are. Another line runs through French. In English the political sense of a governing committee comes from French "directoire", a semantic loan, so the same Latin-derived word carries both a religious handbook and a revolutionary council in its history.
