-Prefect of the Council =
Bltmojadaék Prfek (-ék/-aék = possessive), or alternatively
Bltmojadaék Wli (from Turkish
Vali = "
Wāli");
-Federal =
Prtastaték; for Federation I would suggest
Prtakns, from
Prtastat, Brmek for region, and by analogy with
Rekvakns ("Republic");
-Federal States is a bit trickier, since the Brmek word for Federal is derived from the word meaning "sub-national division; region", and thus "State as part of a federation", so Federal State would be translated as
Prtastaték Prtastat, which is very redundant. So I guess it would be ok to use the word Knstat here, in which case you have
Prtastaték Knstat;
-Chamber of Deputies =
Srnebrjohikoék Meclis (from
Srnebrjohiko = "representative" +
Meclis = "parliament, assembly")
-Banded States of Vanuku =
Wrnukék Pntezi Knstat;
-Governor General =
Hákm-Seik'rsyiji (from Arabic
ħākim = "governor" +
Seik'rsyiji = "universal").
The link posted by Zanz has a number of words that are primarily relevant for Jelbek, and not for Brmek or Pntek, because their source language is Deltarian. For loan words, Brmek prefers Turkish, Arabic, Persian, and (I assume) Hebrew.
Hope that was helpful.
