'mistakenly-provided' originates from the combination of 'mistakenly' and 'provided', where 'mistakenly' is derived from 'mistake', meaning 'an error or fault', and 'provided' is the past participle of 'provide', meaning 'to supply or make available'.

'Mistakenly' evolved from the Old English 'mistacan', meaning 'to err', and 'provided' from the Latin 'providere', meaning 'to foresee or supply'.

Initially, 'mistakenly' meant 'in error', and 'provided' meant 'supplied'. Together, they convey the idea of something being supplied in error.
