Pronunciation

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

Forms

sēgregō (present infinitive sēgregāre, perfect active sēgregāvī, supine sēgregātum); first conjugation[1] Lucretius splits it by tmesis, sēque gregārī.[2][3]

Etymology

It is from Latin sē- (“apart”) + grex (“flock”) + -ō, “to set apart from the flock”.[2][1][4] De Vaan explains it as built on a phrase ⟨*sē grege⟩ “beside the herd”, as ēgregius is on ⟨*ē grege⟩.[5] He traces grex to Proto-Italic *gʷreg- and Proto-Indo-European *gʷreg- (“group, herd”).[5]

Earliest recorded meaning

Plautus has it first,[5] in the Miles Gloriosus of a man who scorns some women and sets all the others apart except the one addressed.[2]

Semantic evolution

Its general sense is to separate or exclude: Terence has a plea not to cut oneself off from a woman, and Livy prisoners led out and divided.[3] Lewis & Short note that the literal sense, setting apart from the flock, is very rare: Phaedrus has sheep separated from goats.[3] Figuratively Cicero separates savagery from humanity and virtue from the highest good.[3] Seneca uses it of setting aside a topic.[2] The Vulgate has the shepherd who separates the sheep from the goats,[3] and Church Latin keeps “separate, set aside”.[6] English segregate was formed from its past participle in the 1540s.[4]
