"Look not mournfully into the past. It comes not back again," wrote Henry Wadsworth Longfellow in his 1839 novel Hyperion. But these days the past is trendy, old-fashioned is hip, and retrospective is as retro as it gets. A glance at the history of retrospective reveals that it traces back to the Latin retro- (meaning "back," "behind," or "backward") and specere (meaning "to look at"). Once you have retrospective behind you, you can also add its kin retrospect (which is used as a noun, an adjective, and a verb) and retrospection to your vocabulary, too. Retrospective can also be used as a noun, referring to an exhibition that "looks back" at artistic work created over a span of years.
