Formation
Derivation
First attested
c. 250–184 BC, Plautus
Ultimate origin
Proto-Indo-European (*deiḱ-)

Forms

diciō f (genitive diciōnis); third declension[1] It is found only in the oblique cases of the singular, with one plural in Prudentius;[2] the spelling ditio is less correct.[2]

Etymology

It is formed with the suffix -iō from the root ⟨dic-⟩ of dīcō (“to say”).[3][1][4] De Vaan derives the verb from Proto-Italic *deik-e/o- (“to say”) and Proto-Indo-European *deiḱ-e/o- (“to show”).[5] The TLL compares dicis, dictātor and condiciō.[6][2]

Earliest recorded meaning

Köbler's first author is Plautus,[4] where the defeated enemy surrender themselves, their city and their children “into the dominion and judgement” of the Theban people.[2]

Semantic evolution

It is a political and military term for dominion, sovereignty or sway, as in Caesar's states brought into the power of the Roman people and Livy's surrender of everything into Roman hands.[3][2] Of private persons it is authority or control, as Plautus' “I give my ears into your control” and Pliny the Younger's children in their parents' power.[3]

Church Latin glosses it “domination, power, control, jurisdiction”.[7] In medieval Latin fiscī diciōnēs is the fisc as a corporate body.[8]
