'nut-flavored' originates from English, formed by combining 'nut' (from Old English 'hnutu') and the past participle adjective 'flavored' (from Old French 'flavor' < Latin 'flāvor'), where 'nut' meant 'an edible seed' and 'flavor' meant 'taste or aroma.'

'nut-flavored' developed in Modern English as a compound adjective: Old English 'hnutu' became Middle/Modern English 'nut,' while Old French 'flavor' (influenced by Latin 'flāvor') entered Middle English as 'flavour'/'flavor'; adding the suffix '-ed' to 'flavor' formed 'flavored', leading to the compound 'nut-flavored'.

Initially, it meant 'having the taste of nuts,' and this meaning has remained stable in modern usage.
