Sanhedrin (English)

Where does "Sanhedrin" come from?

The English noun 'Sanhedrin' was borrowed from Hebrew 'סַנְהֶדְרִין'[1]. The Hebrew term itself derives from Ancient Greek 'συνέδριον'[1][3], meaning 'sitting together, hence assembly or council'[1]. This Greek word is formed by combining 'σῠν-' meaning 'with' and 'ἕδρᾱ' meaning 'seat' or 'session'[2][5]. Going back even further, the Greek 'ἕδρᾱ' traces through Proto-Hellenic '*hédrā' and Proto-Indo-European '*sedreh₂' to the root '*sed-', meaning 'to sit'[4]. Through these stages, a word built on the simple concept of sitting together evolved into a term for a judicial assembly. The English word also shares a doublet relationship with 'synedrion'.

The ultimate Proto-Indo-European origin stems from the reconstructed root '*sed-', which is a linguistic reconstruction. [4]
