Loglan

n. artificial language that James Cooke Brown designed and developed in the late 1950s

This article is about the constructed spoken language. For the programming language, see Loglan 88. Loglan is a constructed language originally designed for linguistic research, particularly for investigating the Sapir-Whorf Hypothesis. The language was developed beginning in 1955 by Dr. James Cooke Brown with the goal of making a language so different from natural languages that people learning it would think in a different way if the hypothesis were true. Loglan is the first among, and the main inspiration for, the languages known as logical languages, which also includes Lojban and Ceqli.

<human language> (Later "Lojban" /lozh'bahn/) An artificial human language designed by James Cooke Brown in the late 1950s.
Most artificial human languages devised in the 19th and 20th centuries (e.g. Esperanto) were designed to be easy to learn. Loglan, however, is unique in that its chief design goal was to avoid synactic ambiguity -- the kind that arises when trying to parse sentences like "The blind man picked up the hammer and saw".
Loglan is thus the only human language unambiguously parseable by a formal grammar (assuming you count Loglan as a human language; its grammar is not at all like that of any natural human language).
Most later development on Loglan continued under the name "Lojban".
The Loglan Institute, Inc. is a non-profit research corporation.
Loglan is apparently unrelated to the programming languages Loglan'82 or Loglan-88.
