What a horror of incorrect usage of the English language. My comment isn't a comment on the writer, but rather my reaction to sheer number of incorrect usages of the English language, and the educational system that allows a person to pass a class while not grasping the material.

There's no such thing as, 'more correct', there is correct and incorrect, and in some cases, preferred or non-preferred.

It is, passersby, not passerbys. The plural of the word is used on the root or main word, in this case, passer. It's like using the plural of attorney general, which is attorneys general, not attorney generals. It's the word attorney that is plural, not the word general.

And there is no such thing as a general concensus. By definition a concensus is a general, or majority opinion or agreement.

I hoping that you're very young. I suspect not though, as these words are generally not used by very young people. What concerns me is that I hear people say, or read comments where they think that if they are, "...not in English class, what difference does it make?" as to whether their use of English is utterly garbled. If you don't understand the correct use of English, you'll not be able to fully comprehend any reading that you may undertake (and reading is fun), or may need to do. You will not understand the world around you nearly as well as someone who knows and understands the correct usage of the language. I see some words so rarely used outside of good literature these days, and these are not obscure words, that if I use such a word in my writing, autocorrect or whichever grammar or spell-check program is functioning, will try to change my word to an incorrect form of the word for the context in which I'm using it.

Failing to understand the correct usage of English, makes the same difference as using math incorrectly. Incorrect English is propagated by its incorrect usage. Allowing our language or the knowledge of it to degenerate will continue a spiral, resulting in people struggling to understand each other. There's little in life more important than the ability to communicate with others effectively.
