'sporeless' originates from the English word 'spore' combined with the suffix '-less', where 'spore' refers to a reproductive cell capable of developing into a new individual without fusion with another cell, and '-less' means 'without'.

'spore' changed from the Greek word 'spora' meaning 'seed' and eventually became the modern English word 'spore'.

Initially, 'spore' meant 'seed', but over time it evolved into its current meaning of 'a reproductive cell'.
