'locally-sourced' originates from the combination of 'local' and 'source,' where 'local' meant 'pertaining to a particular place' and 'source' meant 'origin or point of supply.'

'local' and 'source' were combined in modern English to form the compound adjective 'locally-sourced.'

Initially, it meant 'obtained from a specific place,' and this meaning has largely remained the same in modern usage.
