'anagennesis' originates from Greek, specifically the word 'ἀναγέννησις' (anagénnēsis), where 'ana-' meant 'again' and 'gennēsis' meant 'birth' or 'origin'.

'ἀναγέννησις' (anagénnēsis) was adopted into Late Latin as 'anagennesis', and eventually became the modern English word 'anagennesis'.

Initially, it meant 'rebirth' or 'regeneration', and this meaning has largely remained the same in modern usage, especially in spiritual or philosophical contexts.
