Ultimate origin
Proto-Indo-European (*se-ḱuo-)

Pronunciation

  • Classical: [sɛˈkʷɛs.tɛr][1]
  • Ecclesiastical: [seˈkʷɛs.ter][1]

Forms

sequester m (genitive sequestris or sequestrī, feminine sequestra); variously declined, third declension, second declension[1] The OLD treats it as an adjective, sequester, -tra, -trum, also sequester, -tris, -tre.[2]

Etymology

It is a derivative of secus (“otherwise, beside”) with the contrastive suffix ⟨-ter⟩, from an older ⟨*sequos⟩.[2][1] Wiktionary compares the same suffix in magister and minister.[1] De Vaan lists it among the derivatives of that adverb, which he traces to Proto-Italic *sekwos (“separate”) and, following Klingenschmitt, to Proto-Indo-European *se-ḱuo- (“by oneself, separate”), comparing Old Irish sech (“past; without”); the older explanation took the adverb as an old participle "following", from the root of sequor.[3] Köbler connects it with that verb too.[4]

Earliest recorded meaning

De Vaan finds it first in Plautus.[3] In the Rudens someone refuses to let the other take a thing away unless he names a depositary or an arbiter, and in the Mercator it is said that a woman was given to someone in trust.[2]

Semantic evolution

It is first a term of law: a third party to whom disputed property was entrusted until the dispute was settled, a depositary, as in Plautus, Cato, Petronius and the jurists.[2][5] The neuter is used in sequestrō pōnere or dare, to place in trust, which Gellius explains.[2] In elections it was the agent with whom a promised bribe was deposited: Cicero names such agents beside the go-betweens who corrupt juries, and accuses Plancius of having been a seller and agent of bribes for his tribe.[2] From there it came to mean an intermediary in general: Virgil has Trojans and Latins wandering the hills together under a peace that kept them apart, and Seneca calls Menenius Agrippa a mediator between patricians and plebs.[2] Apuleius uses it of an old woman who arranged adulteries.[2] The older form sequester, -trī is ante- and post-classical and poetic.[5] Stelten gives "trustee" for Church Latin.[6]
