What are the pronominals in the Tlingit language?
Tlingit has a complex system of pronominals
Are there any other interesting aspects about Tlingit pronomials besides the complexity of the system?
There are also the independent pronominals which are completely separate from the verb and can be used in dependent clauses or in subject or object position.

Question: What is special about this language>?
