testimony (English)
Where does "testimony" come from?
The English noun 'testimony' is inherited from Middle English 'testimonie', which came through Old French 'testimonie' from Latin 'testimōnium', meaning 'testimony'[1]. The Latin noun is formed from 'testis', meaning 'witness', combined with the suffix '-mōnium', meaning 'obligation'[2]. The word 'testis' ultimately derives from the Proto-Indo-European root '*tréyes', meaning 'three', combined with '*steh₂-', meaning 'to stand', originally describing a third party standing as a witness to a contract or dispute[3].
