In astrology, "cusp" refers to the point where two zodiac signs meet. Just like how different months of the year have different zodiac signs, different days have different signs too. The cusp is where these signs overlap.
Imagine you have two pieces of cake - one is chocolate and the other is vanilla. If you cut a slice that's in between the two flavors, you'll have a slice that has a little bit of both. That's kind of like a cusp in astrology!
People born on a cusp might have traits from both signs. For example, if you're born on the cusp between Aries and Taurus, you might be a bit of a go-getter like an Aries, but also have a love of comfort and stability like a Taurus.
But it's important to remember that astrology is just a fun way to think about personality traits and doesn't necessarily determine your whole life. It's just one piece of the puzzle!
