/rɪˈpʌblɪk/·noun·The anglicised form 'republick' is first attested in English c. 1604 in translations and political treatises. Philemon Holland's 1600 translation of Livy uses 'the common-wealth' but 'republic' appears in cognate texts shortly after. The word gained decisive currency during the English Civil War (1640s–1650s), when John Milton used 'republic' and 'free commonwealth' interchangeably.·Established

When Parliamentkilled Charles I in 1649 and declared a Commonwealth of England, the word became permanently tainted by regicide in royalist minds. When the monarchy returned in 1660, 'commonwealth' lost the argument, and 'republic' — the

As Latin evolved through Late Antiquity and into ecclesiastical and administrative usage, rēs pūblica persisted in legal and theological writing, though political conditions drained it of its original republican valence. The phrase survived as learned vocabulary in clerical and scholarly Latin, awaiting the moment when Renaissance humanists would recover its classical political charge.
