'antiquatedly-performed' originates from the English word 'antiquated,' which comes from the Latin word 'antiquatus,' meaning 'made old' or 'obsolete,' and 'performed,' from the Latin 'performare,' meaning 'to form thoroughly.'

'antiquatedly' evolved from 'antiquated,' which was used in Middle English as 'antiquat,' and 'performed' from Middle English 'performen.'

Initially, 'antiquated' meant 'made old,' and 'performed' meant 'to carry out,' but together they evolved to describe something done in an outdated manner.
