The culture is intensely subtext based. There are different meanings for how you strike someone. They have rituals for all sorts of everyday tasks, each full of right and wrong ways to do things.
Any culture that has that much subtext in it has language taboos.
The episode where they are doing some kind of court case and there is a Klingon lawyer threw my entire perception of Klingons for a loop. If they have lawyers, what other weird jobs do they have you might not expect from a warrior race? Like... How does one find honor as a sanitation worker? They have to have those, right? 🤔
