'weakly-made' originates from the combination of 'weakly,' meaning 'in a weak manner,' and 'made,' the past participle of 'make,' meaning 'to construct or produce.'

'Weakly' and 'made' have been used in English since the Middle Ages, with 'weakly' deriving from Old English 'wēac' and 'made' from Old English 'macian.'

Initially, 'weakly-made' meant 'constructed in a weak manner,' and this meaning has largely remained the same in modern usage.
