From Old French instance ('urgency, effort'), from Latin instantia ('presence, urgency'), literally 'a standing near', from instare ('to stand upon, press upon'), combining in- and stare ('to stand'). First recorded in English around 1340. The logical sense of 'a particular case or example' developed in the early 15th century via Medieval Latin translation of Greek enstasis. The phrase 'for instance' appeared in the 1650s.
