The word "ascendancy" derives from the verb ascend (from Latin ascendere, meaning "to climb or rise," combining ad- "to" + scandere "to climb") and the suffix -ancy (from Latin -antia, denoting a state or condition). The term originally referred to astrological influence (the "ascendant" being the rising sign in astrology) and later evolved to signify general dominance or superiority, reflecting the metaphorical "rising above others."
