Does this language have a name yet? If not perhaps something simple, and something that means "planet earth", like Terran or a variation of the letters TRN, those letters in any order with whatever vowels you want to put before and after the second letter. Not important, but it would be nice to have some kind of name for the language.
what if we have consonantal roots, like in the semitic languages?
e.g.
TaRN = earth (n.)
TaRaNa = to land (infinitive)
maTRaN = landing (n.)
and so on
