'tastefully-combined' is a compound formed from 'tastefully' and 'combined.' 'Tastefully' comes from 'taste' (from Old French 'taster', meaning 'to touch, feel, try, taste') and the adverbial suffix '-fully.' 'Combined' is the past participle of 'combine,' from Latin 'combinare,' meaning 'to unite, join together.'

'Tastefully' evolved from 'taste' plus '-ful' and '-ly,' and 'combined' from Latin 'combinare' through Old French and Middle English. The phrase 'tastefully-combined' is a modern English compound adjective.

Initially, 'tastefully' meant 'in a tasteful manner' and 'combined' meant 'joined together.' The compound now means 'put together with good taste.'
