The phrase "bobbing up" consists of two words: "bob" and "up".
The word "bob" dates back to the early 14th century and originally meant "to move or strike with a quick, jerky motion". It comes from the Middle English word "bobben", which is of unknown origin. Over time, "bob" took on various meanings related to quick, light movements, such as the movement of a bird's head or a float in water.
The word "up" has Old English roots and simply denotes a direction or movement toward a higher position.
Therefore, the etymology of "bobbing up" can be understood as the combination of "bob", meaning a quick, jerky motion, and "up", indicating the upward direction of the movement.
