Origin & History of “session”

Etymologically, a session is simply a ‘sitting’. The word comes via Old French session from Latin sessiō, a derivative of sedēre ‘sit’. Its sense development reflects the symbolic association of ‘sitting down’ with the conducting of business, which can be seen anew in the modern English expression get round a table. other English descendants of Latin sedēre, which is closely related to English sit, include assess, assiduous (16th c.), insidious (16th c.), séance (19th c.), sedentary (16th c.), sediment (16th c.), size, subsidy (14th c.), and supersede.
