  • US: /ˌsiːkwəˈstreɪʃ(ə)n/, /ˌsekwəˈstreɪʃ(ə)n/[1]

Etymology

It is inherited from Middle English sequestracioun, also sequestracoun,[2][3] borrowed from Old French sequestracion[2][3][4] and directly borrowed from Late Latin sequestrātiō (“a depositing, a sequestering”).[5][3][6][7] The Anglo-Norman word is recorded from 1352, meaning the confiscation of goods or revenue.[8] The Late Latin noun is formed from sequestrātus, the past participle of sequestrō (“to place in safekeeping; to remove, separate”),[6][7][9][3] from sequester (“depositary, trustee, mediator”), the person into whose hands a disputed thing was placed until the dispute was settled.[3][10] Etymonline takes sequester as probably related to sequor (“to follow”), from Proto-Indo-European *sekʷ- (“to follow”),[3][10] while the OED derives it from a form meaning "a position apart", the source of secus (“otherwise”).[5] The OED compares Spanish secuestracion, Portuguese sequestração and Italian sequestrazione.[5]

Earliest recorded meaning

Separation or exclusion, and banishment, especially a cutting off from the privileges of church membership: c. 1425, in the Apology for Lollard Doctrines, which speaks of a curse that is a sequestracoun of þe iust man fro comyn.[5][2] Etymonline dates the word to about 1400.[3]

Semantic evolution

In Middle English the word was also used for putting a matter aside or deferring it, for the lawful impounding of church goods, and in surgery for an eruption around a boil.[2] From the 1560s it meant the state of being sequestered, seclusion or retirement,[5][3] and it gathered a range of legal senses: the diversion of a property's income to satisfy claims against its owner (1565), the seizure of a subject's possessions by the state (1568), the securing of a dead person's goods when the executors renounced probate (1591), and in Scots law the placing of a bankrupt's estate under a trustee (1765).[5] Johnson (1755) gave four senses: separation or retirement, disjunction, the state of being set aside, and deprivation of the use and profits of a possession, quoting Shakespeare for the first and third.[11] The sense of excommunication is now rare.[4][5] In 1948 chemists adopted the word for the removal of ions from a solution by binding them into complexes.[5][12]
