'''Loglan''' is a [[Logical language|logical]] [[constructed language]] originally designed for linguistic research, particularly for investigating the [[Sapir–Whorf hypothesis]]. The language was developed beginning in 1955 by Dr.&nbsp;[[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. In 1960, ''[[Scientific American]]'' published an article introducing the language.<ref>Brown, James Cooke (1960). "[http://members.home.nl/w.dijkhuis/loglan_jcb/Brown_JC_loglan.html Loglan]". ''[[Scientific American]]'' '''202''':43–63.</ref> Loglan is the first among, and the main inspiration for, the languages known as [[Engineered language|logical languages]], which also includes [[Lojban]].

Brown founded '''The Loglan Institute''' (TLI) to develop the language and other applications of it. He always considered the language an incomplete research project, and although he released many publications about its design, he continued to claim legal restrictions on its use. Because of this, a group of his followers later formed the [[Logical Language Group]] to create the language Lojban along the same principles, but with the intention to make it freely available and encourage its use as a real language.

Supporters of Lojban use the term ''Loglan'' as a generic term to refer to both their own language and Brown's ''Loglan'', referred to as "''TLI Loglan''" when in need of disambiguation. Although the non-[[trademark]]ability of the term ''Loglan'' was eventually upheld by the [[United States Patent and Trademark Office]], many supporters and members of The Loglan Institute find this usage offensive and reserve ''Loglan'' for the TLI version of the language.
