'accurately-controlled' originates from the combination of 'accurate' and 'control', where 'accurate' comes from Latin 'accuratus', meaning 'done with care', and 'control' from Old French 'contreroller', meaning 'to check or verify'.

'accurate' evolved from the Latin 'accuratus' through Middle English, while 'control' transformed from Old French 'contreroller' to the modern English 'control'.

Initially, 'accurate' meant 'done with care', and 'control' meant 'to check or verify'. Over time, 'accurately-controlled' evolved to mean 'managed with precision'.
