@Konchog Trying Sesotho -> English it confirms kolo means wheel, but tells me the origin language of it was czech...? -> I believe you and understand your thoughts. I just wanted to tell you, that even if someone IS on the right track, he might give up on it. Because if you don't speak this language how would you find out the word kolo exists?
I liked the idea of the puzzle and kind of wanted to tell you which problem I had, because I had the right idea very soon. But that doesn't help if tranlators don't confirm it (in the direction I had to search, English or German -> Sesotho).
