'poorly-wrapped' originates from the combination of 'poorly,' meaning 'in a poor manner,' and 'wrapped,' the past participle of 'wrap,' meaning 'to cover or enclose.'

'poorly' and 'wrapped' have been used in English since the Middle Ages, with 'poorly' deriving from 'poor' and 'wrapped' from the Old English 'wrappan.'

Initially, 'poorly' meant 'in a poor condition,' and 'wrapped' meant 'to cover.' The combination has maintained its meaning of 'not well covered.'
