The compound "stone-throwing" is a transparent combination of two ancient Germanic roots. "Stone" derives from the Proto-Germanic stainaz, a term of solid permanence, while "throw" originates from the Proto-Germanic þrēaną, meaning "to twist" or "to cause to turn," which evolved to signify the act of propulsion. The suffix "-ing," from Proto-Germanic -ingō, -ungō, creates deverbal nouns denoting an action or its result. The literal logic of "propelling rocks" has been applied concretely to describe a primitive weapon, a form of public dissent, and even a casual pastime, with the modern abstract meaning encompassing any organized or spontaneous act of hurling stones.

Structure: stone (object) + throw (action) + ing (noun suffix) - stone: From Old English stān, meaning "rock, stone."
