'aristogenic' originates from Greek elements: 'aristos' and the suffix '-genic'. 'aristos' meant 'best' and the element '-genic' (from Greek 'genēs'/'genos') meant 'producing' or 'born'.

'aristogenic' is a modern English formation built from the Greek-derived prefix 'aristo-' and the combining form '-genic' (via Neo-Latin/Modern coinage); there is no distinct medieval English ancestor for this exact word.

Initially the Greek components conveyed the idea of 'producing or relating to the best'; in English usage the compound has come to mean 'originating in or favoring an aristocracy' or 'tending to produce an elite.'
