Formation
Derivation
First attested
81–43 BC, Cicero
Ultimate origin
Proto-Indo-European (*deh₃-)

Forms

dēditus (feminine dēdita, neuter dēditum, superlative dēditissimus); first/second-declension adjective[1]

Etymology

It is the participle of dēdō (“to give up, surrender”), used as an adjective.[1][2] The verb is from dē- (“away”) and dō (“to give”), which de Vaan derives from Proto-Indo-European *deh₃- (“to give”).[3][4]

Earliest recorded meaning

Köbler gives Cicero as its first author,[2] who calls Crassus too devoted to the equestrian order, in the Brutus.[1]

Semantic evolution

It is devoted or attached to a person or group, and given over to an activity, as Cicero's men given to frivolous love affairs; of an activity it is directed to one thing, as Cicero's constant practice devoted to a single subject.[1][5] It takes a dative, in with the ablative, or an adverb.[1]

The TLL records the phrase dēditā operā, “deliberately, on purpose”, which Festus explains as “very much given”.[6]
