Amazon
river and company name
Today this word meansThe South American river — and the company named after it.
The company took its name straight from the world's largest river.
The river's name, the record goes, came when a 16th-century expedition reported fighting bands of bow-wielding women warriors and likened them to the Amazons of Greek myth.
Worth noting
The link runs company → river → myth, indirectly. Skip a step and say "Amazon took its name from myth," and it becomes wrong.
