the.com/instance
A class is the recipe; an instance is the actual casserole you have to clean up.
means A specific, single occurrence of something — one concrete example pulled out of a general category or case.
from From Latin instantia, meaning 'presence' or 'urgency,' itself from instare, 'to stand upon or press forward' (in- 'upon' + stare 'to stand'). It originally carried the sense of an urgent, pressing case at hand — something standing right before you — and drifted over centuries into meaning simply 'a particular case or example,' the one instance standing in for all the others.
