ad-vance-ment, ad-vanc-ing
Phonetic: /ədˈvæns.mənt, ədˈvæn.sɪŋ/
In Medieval astrology, advancement or advancing refers to a planet moving toward an aspect, condition, or position that increases the development of a matter.
This concept is especially important in horary and predictive astrology, where an applying planet indicates movement toward perfection and completion. Advancing motion can strengthen the connection between significators and show progress, agreement, or unfolding events. Medieval astrologers examined the speed, condition, and dignity of the advancing planet to judge whether the matter would proceed successfully. The idea reflects the importance of planetary motion in determining outcomes over time.
