'straightforwardly-controlled' originates from the combination of 'straightforwardly' and 'controlled'. 'Straightforwardly' comes from 'straightforward', which means 'direct and clear', and 'controlled' comes from 'control', meaning 'to regulate or manage'.

'Straightforwardly' evolved from 'straightforward', which was used in Middle English as 'streitforþ', meaning 'direct'. 'Controlled' comes from the Old French 'contreroller', meaning 'to check or verify'.

Initially, 'straightforwardly' meant 'in a direct manner', and 'controlled' meant 'regulated'. Together, they imply a direct and uncomplicated form of management.
