The full enclosure of a sign within a
house that has two other signs on cusps – for example, if the 2nd house cusp is at 23°
Aquarius, and the 3rd house cusp at 6° Aries, Pisces is intercepted
within the 2nd house and any planets in Pisces may be described as
being within an intercepted sign. Modern authors have suggested that planets in
intercepted signs are weakened or in some way confined, though this view does
not appear to be supported in traditional texts.
