The Far Horizons: The Far Horizons is a 1955 American western film directed by Rudolph Maté, starring Fred MacMurray, Charlton Heston, Donna Reed and Barbara Hale.  It is about an expedition led by Lewis and Clark, which is sent to survey the territory that the United States has just acquired in the Louisiana Purchase from France.  They are able to overcome the dangers they encounter along the way with the help of a Shoshone woman named Sacagawea.  This is currently the only major American motion picture on the Lewis and Clark expedition (although there have been television documentaries on the subject).  Many details are fictional, and the minor scene where the group reaches the Pacific Ocean reflects the low budget of the film.

Speedtalk: Speedtalk is a fictional constructed language and key plot device in Robert A. Heinlein's novella "Gulf" (1949).

A single phoneme indicates a word, so a "word" indicates a sentence.  In the only example given, a "word" means ""The far horizons draw no nearer.""
