Evidence of presolidification, the counterpart to premelting, is reported. Near the eutectic temperature, TC, the propagation direction of thermal gradient driven motion of eutectic Ge-Pt droplets on Ge(110) is determined by presolidification. Well above TC, the micron-sized droplets move towards the hottest location at the substrate, irrespective of crystalline direction. At 90 K above TC, a strong, unanticipated preference for propagation along the substrate [001] azimuth suddenly emerges, which is attributed to presolidification at the liquid-solid interface. The propagation along [001] is accompanied by a distinct change in shape from compact to elongated along [001].
