To speed up a process or make something happen more quickly. To accelerate the progress of an action or procedure.
From the same Latin root as expedient - expedire, meaning 'to free the feet.' The Romans used this term for removing obstacles that slowed down marching soldiers. It evolved to mean clearing any impediments to swift action.
Remember 'expedite' by thinking of FedEx - they expedite packages! Both share that sense of urgent speed. The 'ped' in the middle relates to feet (like pedestrian), suggesting moving your feet faster.
