'wrongly-held' originates from the combination of 'wrongly,' meaning 'incorrectly,' and 'held,' the past participle of 'hold,' meaning 'to believe or maintain.'

'Wrongly-held' combines the adverb 'wrongly' with the past participle 'held' to form an adjective describing incorrect beliefs.

Initially, it meant 'incorrectly maintained,' and this meaning has largely remained the same in modern usage.
