Morphology

big + Sioux + river

The name is compositionally built from literal words: 'big' (large) + 'Sioux' (the Native American group) + 'river' (a watercourse), so a learner who knows the constituents can infer it refers to a (relatively large) river associated with the Sioux. As a descriptive proper name the exact geographic details are arbitrary but the basic meaning is directly derivable and follows common naming patterns cross‑linguistically.

Etymology

Big Sioux River comes from the Sioux people who lived along it long ago. The word Big was added to show it is larger than the nearby Little Sioux River, so the name tells you both who lived there and that it is the bigger river.
