A cusp is like being on the edge of something significant, the point where one phase transitions into another. Think of it as the moment right before a big change, like the instant before you turn 18. It's that in-between space, not quite here, not quite there. A cusp can refer to a pointed end, like the cusp of a tooth. Figuratively, being on the cusp implies anticipation and uncertainty. It's where possibilities are about to unfold, a bit like waiting for a critical plot point in your favorite series.
