'evenly-combined' originates from the words 'evenly' and 'combine'. 'Evenly' comes from Old English 'efen', meaning 'level or equal', and 'combine' comes from Latin 'combinare', where 'com-' meant 'together' and 'bini' meant 'two by two'.

'Evenly' evolved from Old English 'efen' to Middle English 'even', and 'combine' evolved from Latin 'combinare' to Middle English 'combinare', eventually forming the modern English 'combine'.

Initially, 'evenly' meant 'level or equal', and 'combine' meant 'to join together'. Over time, 'evenly-combined' evolved to mean 'mixed or blended in a uniform manner'.
