This means phrases with “of” or ‘s in them in English.
There are two ways to go about this in Thalas’sian. The first is to simply place the words side by side, like so:
Noun [of] Noun
Alaa Belore – Light of the Sun / the Sun’s light Ban thalas’re – Gate of my home / my home’s gate Sinu aran dor – Good city of stone Din thalas’na – Land of our home
Or, you can treat the “of Noun” part like an adjective, prefixing it onto the other noun, like so:
Belore’alaa – Sun-light Thalas’ban’re – My home-gate Sinu dor’aran – Good stone-city Thalas’din’na – Our home-land
When you do this, they become a compound word. As you see in “Thalas'ban're” and “Thalas'din'na”, the possessive pronouns are put at the end of the new compound, not after “Thalas”. This is also visible in “Sinu dor'aran”, wherein the adjective “sinu” is put at the beginning of the phrase, not between “dor” and “aran”.
