'harmoniously' originates from the Greek word 'harmonia,' meaning 'agreement or concord,' and 'connected' from the Latin 'connectere,' meaning 'to bind together.'

'harmoniously' evolved from the Old French 'harmonieus,' and 'connected' from the Middle English 'connecten.'

Initially, 'harmoniously' meant 'in agreement,' and 'connected' meant 'joined together,' which has largely remained the same.
