I am a linguistic anthropologist and I create fictional languages (conlangs) as a hobby. I have language background in German, English, and Japanese.
Fictional languages like Elvish, Klingon, Dothraki, or Na'vi can add depth and life to your characters. You can use it to name people or places, create historical or cultural documents, or even have full-blown conversations. Readers can have fun with decoding.
Provide me with an explanation of the culture and landscape your characters inhabit and some inspiration languages you would like this language to evoke and I can provide...
For just $5 I will create a sketch of a conlang according to your specifications/inspiration including
Vowel and consonant inventory
For more I can flesh out a language into a more sophisticated form including
Invented words and word roots
Rules for word combination
Invented script for language
Audio/video Pronunciation guide
Book / Ebook
Basic Naming Language
"Naming" includes a sound system, root words, and 10-15 names
