On the Evolution of Language First Annual Report of the Bureau of Ethnology to the Secretary of the Smithsonian Institution, 1879-80, Government Printing Office, Washington, 1881, pages 1-16

This pioneering report from the late 19th‑century Bureau of Ethnology examines how human language grows from a handful of basic words into the complex vocabularies we use today. Drawing on a careful study of several Native American tongues, the author maps the ways speakers combine, compound, agglutinate, and inflect words to convey ever‑more nuanced ideas. The essay highlights that new concepts rarely require entirely new words; instead, existing material is reshaped and recombined.

Readers are guided through concrete examples—juxtapositions that retain separate meanings, seamless compounds like “rain‑bow,” slight fusions such as “holiday,” and heavily altered inflections that become almost unrecognizable. By tracing these grammatical processes, the work reveals a pattern of economical change that shapes every language’s evolution. The analysis offers a clear window into the underlying mechanisms that turn simple sounds into the rich sentences of modern speech.
