Laos Etymology

In the Lao language, the country's name is "Muang Lao". The Imperial French, who made the country part of French Indochina in 1893, spelled it with a final silent "s", i.e. "Laos" (The Lao language itself has no final 's' sound, so Lao people do not pronounce the word Laos). The usual adjectival form is "Lao", e.g. "the Lao economy", not the "Laotian" economy--although "Laotian" is used to describe the people of Laos to avoid confusion with the Lao ethnic group.
