'nutrient-enriching' is a compound of 'nutrient' and 'enriching'. 'Nutrient' originates from Latin, specifically the verb 'nutrire', where the root meant 'to nourish'. 'Enrich' originates from Old French 'enrichir', built from the prefix 'en-' (to make) and 'riche' meaning 'rich'.

'nutrient' entered English via Late Latin/French scientific usage (19th century) from Latin 'nutrire'. 'Enrich' came into English from Old French 'enrichir' (Middle English period), and the present participle form 'enriching' has been used to form adjectival compounds (e.g., nutrient-enriching) in modern English.

Initially, the components meant 'to nourish' (nutrire) and 'to make rich' (enrichir); over time they combined into modern compound uses meaning 'to add or supply nutrients' and the compound now specifically conveys 'making something richer in nutrients.'
