'reliably' originates from 'reliable,' which comes from the French word 'reliable,' meaning 'to rely.' 'Designed' comes from the Latin word 'designare,' meaning 'to mark out.'

'Reliable' evolved from the French 'reliable' and 'design' from Latin 'designare,' eventually forming the modern English term 'reliably-designed.'

Initially, 'reliable' meant 'able to be relied upon,' and 'design' meant 'to mark out.' Over time, 'reliably-designed' evolved to mean 'constructed with consistent dependability.'
