'faultily-edited' originates from the combination of 'faultily,' an adverb form of 'faulty,' and 'edited,' the past participle of 'edit.'

'faultily' comes from the Old French word 'faute,' meaning 'lack' or 'deficiency,' and 'edit' comes from the Latin word 'editus,' meaning 'to publish.'

Initially, 'faultily' meant 'in a faulty manner,' and 'edited' meant 'prepared for publication.' Together, they describe something prepared for publication in a faulty manner.
