'market-determined' is a compound of 'market' and 'determined'. 'market' originates from Old North French, specifically the word 'marché' (from Latin 'mercatus'), where the root 'merc-' meant 'trade' or 'commerce'. 'determined' originates from Latin, specifically the word 'determinare', where 'de-' meant 'completely' and 'terminare' meant 'to bound or limit'.

'market' changed from Old North French 'marché' (and related Old English forms) and eventually became the modern English word 'market'. 'determined' changed from Latin 'determinare' through Old French 'determiner' into Middle English 'determine' and became the modern English past-participle/adjectival form 'determined'. The compound 'market-determined' is a modern English formation combining these elements.

Initially, 'market' referred to a place or assembly for buying and selling and 'determine' meant 'to set limits or decide'; over time, combining them produced the adjectival sense 'determined by market forces', which is the current meaning.
