Etymology

The word "group" entered English in the late 17th century from French groupe, meaning a "cluster" or "knot." The French term derived from Italian gruppo, which originally referred to a "knot of people" or "cluster of objects." This Italian word likely traces back to Germanic roots, possibly related to Proto-Germanic kruppaz ("lump, mass"). Over time, "group" expanded from its physical sense of clustering to abstract groupings (e.g., social, scientific). The spelling preserved the French -ou- but simplified the ending.
