'aniline-derived' is a modern English compound formed from 'aniline' + the past-participle adjective 'derived'. 'aniline' itself entered English in the 19th century from French 'aniline', ultimately tracing back to 'anil' (indigo), and 'derived' comes from Latin 'derivare' (to draw off).

'aniline' was adopted into scientific English in the early 1800s from French 'aniline' (coined for the chemical isolated from indigo/coal-tar dyes). 'derived' comes via Old French/Latin from Latin 'derivare' (to lead or draw off), and the compound 'aniline-derived' is a straightforward 20th/21st-century English formation combining the noun + past participle to make an adjective.

Originally, 'aniline' referred broadly to substances associated with indigo and dye sources; as organic chemistry developed it came to denote the specific compound aminobenzene. 'Derived' originally meant 'drawn off' or 'led from' and now commonly means 'originating from'; combined, the compound now specifically denotes materials produced from or structurally related to aniline.
