Slender and scrawny. "Slender" connotes grace and desirability, while "scrawny" connotes weakness and unhealthiness. ("Thin" is sort of in the middle as it could be either just "having little flesh" to "having too little flesh".)
It depends on what type of government the country is. Take an example, Great Britain (England, Britain, whatever it is called.) is a monarchy, which means that they have royal families... like how we have the president. (in the U.S at least) It can also be dependent on what the country decides to do, or the president decides. I hope this helps!
