I am glad that you pointed out that our Constitution is also a dictionary.
Where did you come up with the notion anyone was saying the Constitution was a dictionary?
With all due respect, the post you incoherently replied to was directed to the poster of 74 who was making a weird claim about NBC which is not in the Constitution.
In the case of NBC, it is one of the important things in the Constitution that the Founders did not define. Anyone claiming they “know” the definition of NBC is delusional.
