Creating a Language, how hard can it be?

In the beginning there was nothing but a wave, the the wake of the wave worlds came to be and ceased to be, but eventually some of these worlds made waves of themselves, these echo'd through the other worlds, making changes to the wave and all that it spawns, this, to the beings that came of the Wave and now live among it, is called the Astra.
The world of Cinti (unnamed atm) was war struck, those seeking refuge fled north and settled in unstable mountains, this would have been a death sentance, but the instability were echos from the astra, ideas of radical leaps in technology seeping through, so with this knowledge bombarding and to some degree compelling them people of many cultures and ideologies built a bunkered city powered by light (with a massive solar panel dome covering the whole city, both as defense and a power source) and names it Cinti (sin-tee), meaning Of Light.
Cinti is a strange monarchy, the monarchs power is primarly the defending of cinti as opposed to the laws within, the spouse of the King or Queen are referred to as the Lesser Queen / Lesser King, as means to seperate them from the power of the monarch. The laws within are decided, judged and enforced by the Cina (see-nah), meaning under light. Cinti's laws circle around the idea of absolute freedom of arts and science, but the city has a problem with dangerous abuses of these freedoms, often claimed to be the result of madness from the echos of the astra.
In its early history 3 major disputes occur, first was the sharing of their knowledge with the rest of the world, after some light fighting it was decided that the King or Queen (and not the Lesser) would see to it that nobody gets out of the city and nobody gets in without a consultation and if successful an induction.
The second dispute was a matter of taxes, again after some light fighting it was decided tax would not be paid, instead power was purchased and the monarch alone would own the power from the cities dome.
The third dispute was a matter of expansion, with the city laid out and the dome functional if not complete how the city would expand became an issue, this was the first task given to the Cina who saw fit to promote expanding down rather than out, thanks to the incredible technology available this became possible rather quickly but only 2 cities were built, Cinti and the city under Cinti (yet to be named)
