Wolo

Wolo is a term that can refer to multiple, unrelated subjects. In geography, Wollo (often rendered Wolo) denotes a historical province in northern Ethiopia that formed part of the Amhara region in the Ethiopian Empire and later in the federal system. Its major towns included Dessie and Weldiya. The name persists in modern place-names and cultural references, though the provincial system was dissolved during administrative reforms in the 1990s.

In commerce, Wolo refers to Wolo Manufacturing Company, a United States–based producer of automotive horns and warning devices. The company has produced a range of air horns, electric horns, and related accessories for cars, trucks, motorcycles, and marine applications, distributing products through the automotive aftermarket globally.

Less commonly, Wolo may also appear as a personal surname or as a toponym in various languages and regions, reflecting separate linguistic origins.

The term Wolo thus serves as a geographic-historical reference in Ethiopia and as a brand name within the automotive aftermarket, illustrating how a single spelling can denote distinct, unrelated topics across different contexts.
