'aposporic' originates from New Latin, specifically the word 'aposporus', where the Greek prefix 'a-' meant 'without' and Greek 'spora' meant 'seed' or 'spore'.

'aposporic' changed from the New Latin/Neo-Latin word 'aposporus' used in botanical Latin and entered English usage as 'aposporous' and then as the adjectival form 'aposporic'.

Initially it meant 'without spores' in a general sense, but over time it came to refer specifically to the botanical phenomenon of a gametophyte developing from a somatic cell without meiosis (apospory).
