Halakha
The insanely huge corpus of strange religious laws is called Halakha in Judaism. The word root √hlk means “walking”, which is an oddly unspecific word. Presumably, the spooks chose it for some pun: hlk “walking” puns with ḥlq “smoothness”, especially in the sense of “smooth-talking” or a “smooth appearance”. Spookery takes this to the extreme: The spook aristocrats lie about everything, so that they can be ultra-corrupt and still maintain a smooth image.
