'astrogeny' is a modern English coinage formed from Greek elements: 'astron' meaning 'star' and a derivative of Greek 'genesis'/'genos' meaning 'birth' or 'origin'.

'astrogeny' was formed in modern scientific English (20th century) by combining the prefix 'astro-' (from Greek 'astron') with the suffix '-geny' (a back-formation related to Greek 'genesis' and Latinized scientific endings), following patterns like 'phylogeny' and 'ontogeny'.

Initially coined to denote the birth or formation of stars, the term has retained that core sense and is sometimes extended figuratively to mean 'origin' or 'emergence' more broadly.
