The term “ago” in literature acts as a concise temporal marker that anchors past events relative to the narrative’s present, conveying everything from fleeting moments to vast stretches of history. Authors use it to evoke immediacy or nostalgia—for instance, characters recall a conversation “three days ago” ([1]) or reminisce about a pivotal event “a few months ago” ([2]). In some cases, “ago” emphasizes a dramatic contrast, as when a transformation is noted “a moment or two ago” ([3]) or when the vast distance of time is underscored by phrases like “long ago” ([4]) or even “centuries ago” ([5]). Such usages not only situate events in a temporal spectrum but also enhance the narrative’s reflective quality, seamlessly blending personal recollection with historical context.
