cusps
Sharp projecting tips
Cusps are pointed ends where curves meet.
A cusp of a tooth is its pointed projection; a cusp of the moon is either point of a crescent.
In astrology, a cusp is the boundary between zodiac signs—someone born on the cusp falls near the transition.
Figuratively, on the cusp of means at the verge: on the cusp of adulthood, on the cusp of a breakthrough.
