'high-aleurone-content' is a compound formed in modern English from 'high' (Old English 'heah' meaning 'tall' or 'great'), 'aleurone' (from Greek 'aleuron' meaning 'flour'), and 'content' (from Latin 'contentum', via Old French, meaning 'that which is contained').

'high' comes from Old English 'heah' and kept the sense of 'great' or 'elevated'; 'aleurone' was coined in scientific nomenclature from Greek 'aleuron' ('flour') to name the protein-rich layer of seed endosperm; 'content' derives from Latin 'continere' → past participle 'contentum', via Old French into Middle English as 'content', and later used as the noun 'content' (amount contained). These elements were combined in modern English to form the descriptive compound 'high-aleurone-content'.

Initially, the components 'high', 'aleurone', and 'content' retained their separate basic meanings ('elevated', 'flour-like layer', and 'amount contained'), and their combined modern meaning evolved straightforwardly to denote 'a high amount of aleurone layer' in seeds or grains.
