'multi-sporiferous' originates from Latin and Greek elements: 'multi-' from Latin 'multus' meaning 'many', and 'sporiferous' from Greek 'spora' (σπορά) meaning 'seed/seed-like particle, spore' combined with Latin-derived suffix '-ferous' from 'ferre' meaning 'to bear'.

'sporiferous' derives from Greek 'spora' through Latin formations and the Latin suffix '-ferus/-ferous' (to bear), and the compound 'multi-' + 'sporiferous' is a modern scientific coinage combining these elements to mean 'bearing many spores'.

Individually, 'sporiferous' meant 'bearing spores'; with the addition of the prefix 'multi-' the compound specifies 'bearing many spores', a narrower quantitative sense.
