Etymology

It is from Ancient Greek σύνεδρος (súnedros, “sitting together; councillor”) with the suffix -ιον (-ion).[1][2][3] The adjective is formed from σύν (sún, “with”) and ἕδρα (hédrā, “seat”),[1][4] which goes back to Proto-Indo-European *sed- (“to sit”).[5]

Earliest recorded meaning

Herodotus uses it for the council of the allied Greek commanders before Salamis, and for the place where they met.[6][2][7]

Semantic evolution

In Classical Greek it was any council or meeting: a congress of allies (Herodotus, Xenophon, Demosthenes), a council of war, a board of trade, the Areopagus at Athens, and also the place where such a body met.[6][2][8] Plato uses it ironically for a gathering of philosophers.[2] Polybius and Plutarch use it for the Roman and the Carthaginian senates.[6][2]

In the Septuagint it is a council or assembly.[9] In the New Testament and Josephus it is the high council of the Jews at Jerusalem, made up of the high priests, the elders and the scribes, and also the local councils of the synagogues.[4][6] Mishnaic Hebrew took the word as Biblical Hebrew סַנְהֶדְרִין (sanhedrîn), from which English Sanhedrin comes.[4][5] Ignatius of Antioch transferred it to the elders of the church, the “council of God”.[4] Later it was the name of the senate at Constantinople.[6]

The Modern Greek συνέδριο (synédrio) is a learned word for a congress or conference of representatives.[10][3]
