Forms

dīrēctōrius (feminine dīrēctōria, neuter dīrēctōrium); first/second-declension adjective[1][2]

Etymology

It is from Latin dīrigō (“to direct”),[1][3][2] with the suffix -tōrius.[1] De Vaan treats ⟨dīrigō⟩ as a compound of regō (“to direct, guide”).[4]

Earliest recorded meaning

The earliest use is in Rufinus' translation of Origen's commentary on the Song of Songs,[3][2] where the feminine directoria is used as a noun for what seems to be a craftsman's tool for straight lines, like a ruler: if anything in us is crooked, “superducentes directoriam mandatorum dei”, laying on it the straightedge of God's commandments.[3]

Semantic evolution

The Theodosian Code has litterae directoriae, letters that direct or send someone in a given direction.[1] The neuter became the noun dīrēctōrium, a prescribed route.[5][6] In Polish Medieval Latin, Długosz speaks of loca directoria, the places through which a route leads.[7]

Timeline

  • c. 345–411/412 AD – Rufinus uses the feminine as a noun for a straightedge.[3][2]
  • 438 AD – The Theodosian Code has litterae directoriae.[1][2]
