'antimony-derived' originates from English, specifically the element name 'antimony' (from Old French 'antimoine' and Medieval Latin 'antimonium') combined with the past-participle adjective-form 'derived' (from Latin 'derivare', where the prefix 'de-' meant 'from' and 'rivus' meant 'stream').

'antimony' changed from Medieval Latin 'antimonium' and Old French 'antimoine' and eventually became the modern English word 'antimony'; 'derived' comes from Latin 'derivare' through Vulgar/Medieval Latin and Old French into Middle English and eventually the modern English 'derived'. The compound adjective 'antimony-derived' is a modern productive English formation combining the noun + past participle.

Initially 'derived' meant 'to draw off (a stream)' in Latin, but over time it evolved to mean 'obtained from' or 'originating in'; combined with 'antimony' it now specifically means 'obtained from the element antimony' or 'originating from antimony-related sources.'
