'accurately-combined' originates from the words 'accurate' and 'combine'. 'Accurate' comes from Latin 'accuratus', meaning 'done with care', and 'combine' from Latin 'combinare', meaning 'to unite'.

'accurate' changed from the Latin word 'accuratus' and 'combine' from 'combinare', eventually forming the modern English term 'accurately-combined'.

Initially, 'accurate' meant 'done with care', and 'combine' meant 'to unite'. Together, they evolved to mean 'put together with precision'.
