'rarely-created' originates from the combination of 'rarely,' meaning 'not often,' and 'created,' the past participle of 'create,' which comes from Latin 'creare,' meaning 'to make or produce.'

'rarely' changed from Old English 'hrēor,' meaning 'seldom,' and 'created' evolved from Latin 'creare,' through Old French 'creer,' to the modern English 'create.'

Initially, 'rarely' meant 'seldom' and 'created' meant 'to make or produce,' and these meanings have largely remained the same in modern usage.
