Etymology

It is inherited from Proto-Italic *sed-ē- (“to be seated”), inherited from Proto-Indo-European *sed-eh₁- (“to be seated”), a stative verb also found in Sabellic.[2][1] From the same root come sēdēs “seat”, sella “chair” and sēdāre “to settle, calm”.[2]

Cognate with Umbrian sersitu (“let him sit”),[2] and with Old Irish saidid (“sits”), Ancient Greek ἕζομαι (hézomai, “to sit down”), Lithuanian sėdė́ti (“to sit”), Gothic 𐍃𐌹𐍄𐌰𐌽 (sitan, “to sit”) and English sit.[2][3]

Earliest recorded meaning

It is found from Livius Andronicus onwards,[2] whose character is told “stay here and sit until you see me come home”.[3]

Semantic evolution

It meant to sit, of people and of birds perching.[3] It was used of magistrates and judges sitting in office, of armies encamped or lying in ambush, and of peoples settled in a land.[3] Things were said to sit or rest in place.[3]

It meant to sit idle, as in Terence and Cicero, and to stay still.[3] Things came to rest or lodged somewhere, a feeling became fixed in the heart, and a decision was settled, as in Virgil.[3] It also meant to sink or subside, and to lie low or flat.[3] It survives as Italian sedere, Romanian ședea and French seoir, and in Medieval Ibero-Romance Latin it could mean “to be”.[1] English session, sediment and preside come from it.[4]
