This word is used to describe the line between two signs of the Zodiac.
Those with the Sun sign in the last degrees of one sign, or earliest degrees of another are said to be born on the cusp. Astrologers disagree on whether that means the traits two signs are blended or not. It's my opinion that an early Cancer has trailings of Gemini, and a late one, the influence of Leo. And that the twelve pieces of sky do not have fixed borders, but subtle shades of change in energy, as it moves into the next sign.
