'naked-spored' is a modern English compound formed from 'naked' + 'spored', where 'naked' meant 'uncovered, bare' and 'spore' comes from Greek 'spora' meaning 'seed' or 'sowing'.

'naked' goes back to Old English 'nacod' meaning 'bare, uncovered'; 'spore' entered English via Medieval Latin/Greek 'spora' (Greek spora 'seed, sowing'), and the compound 'naked-spored' arose in scientific usage by combining these elements to describe organisms with exposed spores.

Originally, 'spore' primarily meant 'seed' or a unit of propagation; over time, in biology it came to mean the reproductive particle of fungi, algae, and similar organisms. Combined with 'naked' the term came to mean 'having exposed spores' in technical descriptions.
