knuckle
UK: ˈnʌk(ə)l | US: ˈnʌk(ə)l

vt. 3. To strike or press with the knuckles.
The word "knuckle" traces back to Middle English knokel, derived from Old English cnucel (a diminutive form related to "knock" or "lump"). The root knuck- likely imitates the protrusion of a small bone, while -le serves as a diminutive suffix, emphasizing the small, rounded shape of the joint. The word’s evolution reflects a tactile, almost onomatopoeic logic—linking the physical bump to its name.
