Reading more of In the Land of Invented Languages got me to wondering. Here’s what Wikipedia turns up:
- The page on Esperanto has been partially translated into Lojban.
- The Lojban page has been translated into Esperanto.
- Both the Lojban and Esperanto pages have been translated into Simple English (aka “Basic English“).
- The Volapük page has been translated to Esperanto. However, there is only a very minimal Esperanto page in the Volapük wiki.
- Here’s the Wikipedia list of Wikipedias in “Indo-European-based Constructed languages”. Lojban is apparently considered an “A priori Constructed Language”.
I don’t know why; this just tickles my fancy somehow.
Edited to add: In case you were wondering (and I got to wondering after posting that): there was a Klingon Wikipedia, but it was locked by Jimmy Wales in August of 2005. (A non-locked version exists here.)
