Ultimate origin
Latin grex

Pronunciation

  • Classical: [ˈaɡ.ɡrɛ.ɡoː][1]
  • Ecclesiastical: [ˈaɡ.ɡre.ɡo][1]

Forms

aggregō (present infinitive aggregāre, perfect active aggregāvī, supine aggregātum); first conjugation[1]

Etymology

It is from Latin ad- + gregō (“to gather into a flock”), and that verb is made on grex (“flock, herd”).[2][3][1] The epitome of Festus explains it as “to lead to the flock”.[3][4]

Earliest recorded meaning

Its first author is Cicero, who uses it of people joining or being counted with a group: in his speech for Murena he says ego tē semper in nostrum numerum adgregāre soleō, “I always count you among our number”.[2][3][5]

Semantic evolution

Lewis & Short call it a prose word, rarer than adiungō.[4] Caesar and Livy use the reflexive for joining a side or an alliance, Velleius and Tacitus the passive of men joining a party,[2][3] and Valerius Maximus and Seneca use it of counting someone among a class.[2] Cicero also uses it of implicating someone in a charge and of contributing to another's honour.[2] The jurists use it of lumping sums or sureties together.[2]

The absolute use, “to gather, assemble”, belongs to later centuries.[3] Medieval writers used it of admitting members, gathering an assembly and joining lands.[6][7] English aggregate comes from its past participle, about 1400.[8]
