instantiation

20th-century coinage from instantiate +‎ -tion, itself coined 1946 from instance +‎ -ate. The latter, in the sense "a case, an example", from Middle English instance, from Medieval Latin īnstantia (“a being near, presence; also perseverance, earnestness, importunity, urgency”), from Latin īnstāns (“urgent”); see English instant.[1]
