I snooped around after this post and I found the discussion about the transitive/intransitive verb. I've had this doubt before, but I have been unable to find where it was written, so I've asked anyway.
There are a lot of things around and I get lost easy XD
Btw thank you for the answer.
For "athmithrat/ammithrat" probably you're right, but I'm quite sure they don't say "Amm-" because I've seen some tongue between the teeth. But it could be simply a mispronunciation, like many other things :/ Or maybe I've heard something wrong myself.
For "anat", there must be a mistake in the dictionnary. I open every time that linked in the wiki, version 2.06 and under Ammithrar there is "anat", with "to rest" in the same way
For razik ok. I thought that was a "more sure" term.
But I think in the show it's used also another word that is not "hrezef".
