The English word 'delegate' entered the language in the late fourteenth century from Latin 'dēlēgātus,' the past participle of 'dēlēgāre,' meaning 'to dispatch, to assign, to send as a representative.' The compound joins the prefix 'dē-' (from, away) with 'lēgāre' (to send with a commission, to appoint as deputy, to bequeath). The underlying noun is 'lēx' (genitive 'lēgis'), meaning law, and the PIE root is *leǵ- (to collect, gather), which produced both the 'law' and 'reading' branches of Latin vocabulary.
The connection between law and gathering is preserved in the etymology: a 'lēx' was originally a collection of rules, something gathered together. 'Lēgāre' meant to send someone armed with legal authority — a commissioner, an emissary with a mandate. To 'dēlēgāre' was to send such a person away from oneself, transferring authority to them. This legal grounding makes 'delegate' distinct from mere 'representative': a delegate carries formally assigned
In English, both noun and verb forms coexist with different stress patterns. The noun 'delegate' (stressed on the first syllable) denotes the person; the verb 'to delegate' (stressed on the first syllable as well, but with a full vowel on the final syllable) means to entrust authority or tasks. This dual usage — person and action — mirrors the Latin, where 'dēlēgātus' served as both adjective and noun.
The word gained particular political significance in American history. The Constitutional Convention of 1787 was composed of 'delegates' from the states. In American political terminology, delegates to party conventions select presidential nominees. The concept of delegation — transferring power from the people to their representatives — is foundational to republican government, and the word choice reflects its legal Latin heritage.
The broader family of 'lēgāre' and 'lēx' is extensive in English. 'Legate' (a papal or imperial envoy), 'legacy' (something bequeathed, sent to the future), 'legal' (pertaining to law), 'legislate' (to make law), 'legitimate' (in accordance with law), 'privilege' (a private law, from 'prīvus' + 'lēx'), and 'college' (from 'collēgium,' a group of people chosen together for a common purpose) all belong to this family. 'Relegate' (to send back, to assign to a lower position) shares the same structure as 'delegate' but with the prefix 're-' (back) instead of 'dē-' (away).
In computing, 'delegation' has acquired a technical meaning: an object passes responsibility for a task to another object, a metaphor drawn directly from the political and legal sense. This modern extension shows how naturally the concept of entrusting authority to a substitute translates across domains.
Cognates across European languages are closely similar: French 'délégué,' Spanish and Portuguese 'delegado,' Italian 'delegato,' German 'Delegierter.' All preserve the Latin sense of an authorized representative, confirming that the word was transmitted through learned Latin channels rather than evolving through spoken vernacular.
