lie - Wunsch - wish
liet - wünschen - to wish (8)
Not really sure if it is just "li" as the basic aspect of "wish" and the "e" is for the casus. Which could lead to the "t" representing the "he/she/it".

rien - king (8/12)
Maybe "ri" for king and the "en" as an ending for "our" BUT this is kind of a contradiction with "lien" (13), as this, then, should mean "our wish" and the word rien in 8.

Lo va. (15)
Maybe this could also be translated into "Here, (we 've) come.", and there could be also a connection to the french "venir" (come) in "va". "Là" in French is also a prep of place meaning "there".

Maybe Pixie is more related to the French which might help us a bit more to also have the French translation in here. Any French people interested?
