Most certainly indeed.
I have been working on several for the past few months.
Samanese, my most developed. Daalsking, my second most developed. As well as Kuraphi, Tasoullen, Apastinian, and Cheleshian.
For each language I dallied in several other real life languages to get a feel of how they worked.
Samanese for example was highly inspired by Asian languages. And retains a mixture of grammatical rules from Japanese, Korean, and Chinese. As well as a few made up rules.
To keep things simple, the languages are spoken by "anthrozoa" a term for the anthropomorphic races in my story.
Samanese - Largest spoken language, traditionally from Shang Lao on Geobia. A world of anthropomorphic cats.
Daalsking - Second largest spoken language. The origins remain uncertain, but it's spoken by the wolf anthrozoa.
Kuraphi - A language from the Desert of Iskirad on Geobia II, another feline anthrozoadiac language. (Considered indigenous)
Tasoullen - This actually evolved on earth but shares no relation to human languages. Spoken by the fox anthrozoa, it's said to sound like Finnish.
Apastinian - Entirely different story, but is for a lion race called the Leopani. Based off of Greek in sound. But no where near related in grammar.
Cheleshian - Slavic based. Spoken by boring ol' humans.
If anyone is interested in any, or would like to share their language with me. Just message, and I'll get back when I can!
Solu Yohona, Rỳttja! (Ree-tch-Ya!), Яҗeкара (Ya-je-kara), Asinkää masoullen, Thesisfagi, and Spasi.
Guess I could mention those all mean, "Thank you"
