'sloppily-built' originates from the English word 'sloppy,' which comes from the Middle English 'slop,' meaning 'loose, untidy.' The suffix '-ly' is used to form adverbs, and 'built' is the past participle of 'build.'

'sloppy' changed from the Middle English word 'slop' and eventually became the modern English word 'sloppy.'

Initially, 'sloppy' meant 'loose or untidy,' and over time it evolved to describe anything done in a careless or haphazard manner.
