Sense: verb/1
Slip, slide, skid, and glide all describe smooth movement, but differ in control and intention. Slip is always accidental — you slip on a wet floor or a banana peel without meaning to. Slide can be intentional (slide into a seat) or unintentional (the car slid on ice), and often implies continuous contact with a surface. Skid is specific to vehicles or wheels losing traction sideways — a car skids on black ice, but a person rarely skids. Glide suggests smooth, effortless, controlled movement through air or water, with no friction (a boat glides across a lake, a dancer glides across the floor). As nouns referring to mistakes, slip suggests a small, careless accident (a slip of the tongue), while error is more formal and can apply to any kind of wrong decision or calculation. Lapse implies a temporary failure of memory or attention rather than skill (a lapse in concentration). For example: 'I made a slip by calling him by the wrong name' vs 'The computer error cost millions' vs 'His lapse of memory worried the doctor.'

Etymology
The verb 'slip' entered English around the 1200s from Middle Dutch or Middle Low German 'slippen', meaning 'to slide, glide'. By the 1300s it had developed the sense of 'escaping from restraint' (slip one's leash) and 'moving stealthily' (slip away). The noun 'slip' meaning 'piece of paper' came separately from Middle Dutch 'slippe' (a strip cut off), while the underwear sense (early 1900s) was a specialised use of the garment that 'slips' easily over the body. The pottery sense comes from Old English 'slypa' (paste, slime), related to the same root of smooth, sliding movement.
