'unprotectedly' originates from the English prefix 'un-' meaning 'not' and the word 'protected,' which comes from Latin 'protectus,' the past participle of 'protegere,' meaning 'to cover in front.'

'unprotected' changed from the Latin word 'protectus' and eventually became the modern English word 'protected,' with 'un-' added to form 'unprotectedly.'

Initially, it meant 'not covered or shielded,' and this meaning has largely remained the same in modern usage.
