History

Etymology

From astro- (prefix meaning ‘star’) + -gnosy (suffix denoting the scientific knowledge of a subject), modelled on German Astrognosie, or its etymon Late Latin astrognosia, from Ancient Greek ἄστρον (ástron, “celestial body; (specifically) fixed star; planet”) (ultimately from Proto-Indo-European *h2eHs- (“to burn; to glow”)) + -γνωσία (-gnōsía) (from γνῶσις (gnôsis, “inquiry; knowledge”), ultimately from Proto-Indo-European *ǵneh3- (“to know; to recognize”)).
