Forms

dīrēctus (feminine dīrēcta, neuter dīrēctum, comparative dīrēctior); first/second-declension adjective[1] It is also spelled dērēctus.[1]

Etymology

Used as an adjective, it is the perfect participle from Latin dīrigō (“to set straight, direct”).[1][2][3] That verb is dis- with regō (“to direct”), which de Vaan traces to Proto-Italic *reg-e/o- and Proto-Indo-European *h₃reǵ- (“to stretch, direct”).[4]

Earliest recorded meaning

Köbler dates it from the Twelve Tables.[3] Varro speaks of straight rather than projecting teeth.[1]

Semantic evolution

It is not oblique or curved, straight, as Cicero's olive trees in a straight row; moving straight ahead; and in dīrēctum, in a straight line, as in Livy.[1] It is vertical or upright, standing at right angles, as Caesar's upright beams, and sheer, as Cicero's Henna, cut off on every side.[1] Figuratively it is straightforward, direct, undisguised, and of a person forthright.[1] In law it is direct, not depending on an intervening procedure: Julian, Ulpian and Gaius speak of direct grants of freedom and of the dīrēcta āctiō, founded on the strict terms of the law.[1] In Medieval Latin it is direct, immediate; right, righteous; and rightful, and the neuter dīrēctum is a right.[5] Church Latin glosses it direct, guiding, straight, proper.[6] Wiktionary reconstructs a Proto-Romance *dērēctus “straight” from the variant.[7]
