What follows is a diagram of the 2nd amendment. A sentence diagram. I know sentence diagramming isn’t taught in most schools these days (which is a real shame, because it’s great for reading comprehension, which is probably why some people don’t want you to learn it), so I am including some explanatory notes.
Actually diagramming the 2nd amendment puts to rest any argument that the right to own a gun is for militias and not individuals. It drives me crazy when people argue about original intent in favor of the individual right to own guns. This isn’t because they are wrong, but because they overlook this important fact: to come to the conclusion that the right to own a gun is for individuals and not militias, all you need is an understanding of the English language.
Anyway, on the to actual diagram. The subject of this sentence is “right,” namely, “the right of the people to keep and bear arms.” The predicate (the action the subject is taking) is “shall not be infringed.” “A well-regulated militia, being necessary to the security of a free state” is a nominative absolute. It has a noun, but no verb. Grammatically speaking, it has no bearing on the meaning of the rest of the sentence, which is why it is unconnected in the diagram. That first phrase could say anything at all, and the subject and predicate would remain the same.
In short, anyone who believes that the right to keep and bear arms is for militias is ignorant.
