What is the proper adjective for Louisiana?

Answer 1

According to the dictionary the adjective for Louisiana can be "Louisianan" or "Louisianian" with the former being etymologically correct.

Another adjective, from Latin, is "ludovician." But this is used only taxonomically.

Some species of animals and birds have a Latin name containing "ludovicianus" which indicates the species origin or occurrence in Louisiana. Some examples:

- Black-tailed Prairie Dog (Cynomys ludovicianus) "Cynomys" derives from the Greek for "mouse dog" while "ludovicianus" means "from Louisiana"

- Rose-breasted Grosbeak (Pheucticus ludovicianus) "Pheucticus" may derive from the Greek word "pheuticus" meaning shy and retiring" while, again, "ludovicianus" means "from Louisiana" where the bird was first described.
