Language list

Jump to search
This is a list which is maintained by hand, as opposed to Category:Languages which is automatically generated.
Note that languages that are merely jokes even compared to other esoteric languages are located in the joke language list.
Please link only to existing article pages on this wiki. A stub is enough to start with, as long as it has a link to further information. Languages with no link to a description are likely to be deleted.
Non-alphabetic
Due to the large number of various symbols, spacing and punctuation are not ignored in this particular section, although case still is.
