'concerted' originates from the Italian word 'concertare,' where 'con-' meant 'together' and 'certare' meant 'to contend or strive.'

'concertare' transformed into the French word 'concerter,' and eventually became the modern English word 'concerted' through Middle English.

Initially, it meant 'to strive together,' but over time it evolved into its current meaning of 'jointly arranged or coordinated.'
