slide, slip¹glide, coast, skid, slither These verbs mean to move smoothly and continuously over or as if over a slippery surface. Slide usually implies rapid easy movement without loss of contact with the surface: coal that slid down a chute to the cellar. Slip is most often applied to accidental sliding resulting in loss of balance or foothold: slipped on a patch of ice. Glide refers to smooth, free-flowing, seemingly effortless movement: “four snakes gliding up and down a hollow” (Ralph Waldo Emerson) Coast applies especially to downward movement resulting from the effects of gravity or momentum: The driver let the truck coast down the incline. Skid implies an uncontrolled, often sideways sliding caused by a lack of traction: The bus skidded on wet pavement. Slither can mean to slip and slide, as on an uneven surface, often with friction and noise: “The detached crystals slithered down the rock face” (H.G. Wells) The word can also suggest the sinuous gliding motion of a reptile: An iguana slithered across the path.
