'modernly-planned' originates from the combination of 'modernly,' derived from 'modern,' and 'planned,' from the verb 'plan.'

'Modernly' evolved from 'modern,' which comes from the Latin word 'modernus,' and 'planned' is the past participle of 'plan,' which comes from the French word 'plan.'

Initially, 'modern' meant 'of the present time,' and 'plan' meant 'a drawing or diagram.' Over time, 'modernly-planned' evolved to mean 'designed in a contemporary manner.'
