    You Email Greeting Lines Are Wrong, And What Is Even Reality Anymore?

    The universe is a lie. And grammar Nazi porn.

    RE: BUZZFEED LIFESTYLE WRITER

    You start to type an email, and it probably looks something like the below.

    Nothing to see there, right? Wrong.

    Here's why.

    When a person is being addressed in English, the person's name takes what's called the "vocative" case. The vocative case—as in email greetings, for exampe—requires that the person's name being addressed be marked off with a comma.

    So, your email greeting line should actually look like this:

    This pervasive error likely grew out of a misunderstanding of traditional letter greeting lines, which look like this:

    The difference is that "hi" isn't an adjective like "dear" is.

    "Why is there a period after the greeting line rather than a comma?" you ask.

    "But how can 'Hi, Barry.' be a complete sentence? It doesn't even have a verb!" you ask.

    "Wait, but why is 'Dear Barry' followed by a comma?" you ask

    To tie it all together, here are two grammatically correct versions of the two popular greetings:

    I know what you're thinking: I must be a blast a parties.

    Or maybe—just maybe—you're thinking that if your email greeting lines have been wrong all this time, the very fabric of reality itself is in question.

    Or maybe you'd counter that language usage and grammar evolve over time, and that if 99% of people structure email greeting lines a certain way, then that's what's right.
