greetings!

I'm creating a new fictional language which is a combination of Finnish and Hungarian.

My proposed name for this artistic language (artlang) is Samgur, which is a name created by combining letters taken from the native names for these languages, Magyar and Suomalainen (Suomi means Finland in Finnish).

Samgur will feature vowel harmony.

By the way, the languages of Finnish and Hungarian are related, but distantly.
