I just started to read Dune, the terms and content is like bizarre to me. There are special terms without previous introduction of its nature. For example: Muad'Dib, Gom jabber( fortunately, it was later revealed as a poison needle ), quasi-fief, faufreluches, Kull wahad, etc.
If I google them, I will find them in Dune wiki with good explaination, but do I need to look it up?
