'unseeded' originates from the prefix 'un-' meaning 'not' and the word 'seeded', which comes from the Old English 'sǣd', meaning 'seed'.

'unseeded' evolved from the combination of 'un-' and 'seeded', which was used in Middle English as 'seded'.

Initially, it meant 'not having seeds', but over time it evolved to also mean 'not ranked in a competition'.
