Astrosophy

Neologism, formed of the union of two elements: 1. astro (star) and 2. sophy (wisdom).

Astro-/Star

From PIE *ster- (cf. Sanskrit star-, Hittite shittar, Greek aster, astron, Latin stella, Breton sterenn, Welsh seren “star”). Astrological sense of “influence of planets and zodiac on human affairs” is recorded from mid-13c.

Sophy

Word-forming element meaning “knowledge,” from Old French -sophie, from Latin -sophia, from Greek -sophia, from sophia “skill, wisdom, knowledge,” of unknown origin (source: www.etymonline.com).

1. Star derives from Latin astrum, translated from Greek àstron/astér, from Indo-European root *STR-/*STAR, which expresses the idea of spreading (the vision of the stars scattered across the sky).
2. The root of sophy is not yet defined: for the majority of scholars is *SAP-, connected to the idea of juice/flavor/hindsight.

Etymosophy result: wisdom of celestial entities.
