Pronunciation

  • Classical: [diː.reːkˈtoː.ri.ũː][1]
  • Ecclesiastical: [di.rekˈtɔː.ri.um][1]

Forms

dīrēctōrium n (genitive dīrēctōriī or dīrēctōrī); second declension[1]

Etymology

It is from Latin dīrēctōrius (“directing”), its neuter used as a noun.[2] The adjective comes from dīrigō (“to direct”),[3][4] through its participle dīrēctus.[2]

Earliest recorded meaning

It first appears in the Theodosian Code,[4][3] meaning a prescribed route for a journey.[4][5][6]

Semantic evolution

In Medieval Latin Du Cange records it for a sideboard where vessels were set out for banquets (French dressoir),[7] and a British account of 1301 seems to use it for a dresser, a place for dressing meat.[8] It also named an astronomical instrument.[8][9] More often it meant a guide or directive for conduct and a handbook of rules,[8][10][11] and in the Church a directory or ordo, the book of rules for the services, especially around the moveable feasts.[8][12]

English borrowed it in the mid-15th century as “a guide”;[2] from the 1540s the English word also meant a book of rules, especially for Church offices.[2] Italian direttorio came through French directoire from the Late Latin word.[6]
