'non-amino-associated' is a compound formed from three elements: the prefix 'non-' (from Old English 'nān' meaning 'not'), 'amino' (from 'amine', a 19th-century chemical formation ultimately connected to 'ammonia'), and 'associated' (from Latin 'associare', where 'ad-' meant 'toward' and 'sociare' meant 'to join or share').

'non-' developed in Old English as a negative prefix; 'amino' was coined in modern chemical nomenclature in the 19th century from 'amine' (itself named in relation to 'ammonia'); 'associate' came into English via Latin 'associare' → Old French 'associer' → Middle English, yielding modern 'associate' and its past participle 'associated'. The compound 'non-amino-associated' is a modern technical formation combining these elements.

Each element has retained a consistent core meaning ('non-' = not; 'amino' = relating to amines/amino acids; 'associated' = joined or related). Combined, the compound has a transparent, literal meaning: 'not associated with amino (groups/acids)', and this technical sense is stable in contemporary usage.
