'ineffectively-managed' originates from the combination of 'ineffective' and 'manage', where 'ineffective' comes from Latin 'ineffectivus', meaning 'not producing the desired effect', and 'manage' from Italian 'maneggiare', meaning 'to handle'.

'ineffectively-managed' evolved from the combination of 'ineffective' and 'manage', which were used separately in Middle English and later combined in modern English.

Initially, 'ineffective' meant 'not producing the desired effect', and 'manage' meant 'to handle'. Together, they evolved to describe something that is not managed successfully.
