'amygdalin-associated' is a modern compound formed from 'amygdalin' and 'associated'. 'amygdalin' originates from Greek, specifically the word 'amygdalē', where 'amygdalē' meant 'almond'. 'associated' originates from Latin, specifically the verb 'associare', where 'ad-'/'as-' meant 'toward' or 'with' and 'sociare' meant 'to join or unite'.

'amygdalin' entered scientific English via New Latin/French chemical naming (compare French 'amygdaline') and became the modern English chemical name 'amygdalin'. 'associated' came into English through Old French 'associer' from Latin 'associare' and developed into the modern English adjective 'associated'.

Initially, 'amygdalin' denoted an almond-related glycoside (a chemical found in bitter almonds and related seeds); this basic sense remains, now used broadly in biochemical contexts. 'associated' originally meant 'to join or unite with' and evolved into the adjectival sense 'connected with' used in modern compounds like this one.
