ab-sent
Phonetic: /ˈæb.sənt/
A planet is considered absent in Medieval astrology when it is placed in a house where it cannot effectively witness or influence the Ascendant, typically the cadent houses.
In Medieval practice, an absent planet has reduced capacity to act or signify outcomes in a chart. This condition is most often associated with cadent houses, especially the third, sixth, ninth, and twelfth, which were seen as places of weakness or withdrawal from direct action. An absent planet may still signify its natural meanings, but its ability to produce tangible results is limited. Astrologers consider this condition when assessing planetary strength and the likelihood of events manifesting.
