'anilide-associated' originates from English by combining the chemical noun 'anilide' and the past-participial adjective 'associated'. 'Anilide' itself derives from 'aniline' with the chemical suffix '-ide', while 'associated' comes from the verb 'associate' (from Latin).

'anilide' was formed from 'aniline' + '-ide'; 'aniline' entered modern scientific English via French/Spanish 'aniline' from Portuguese/Spanish 'anil', which came from Arabic and ultimately Sanskrit 'nīla' (indigo). 'Associate' comes from Latin 'associare' → Old French 'associer' → Middle English 'associate'. The compound 'anilide-associated' is a modern English technical formation combining these elements.

Initially, 'anilide' denoted a derivative of 'aniline' and 'associated' meant 'joined or related to'; combined, the phrase has the straightforward current meaning 'related to anilide' with little semantic shift beyond the compounding.
