Can you clarify my confusion regarding the usage of the phrases, "as follows" and "as follow"?
AnonymousResponse is:

they are as follow

that is as follows

I don't think so. Please have a look at the posts above yours in this thread and at the following usage note from The Columbia Guide to Standard American English .

Whether the preceding matter is plural or not, as follows is always singular: The reasons for these decisions are as follows. To use as follow instead is sufficiently precious sounding to make your reader break stride: don’t do it. You can use the following instead, but you needn’t. Less stiff would be The reasons for these decisions are these, or Here are my reasons, or My reasons are, first,…, and the like.

I might be wrong but it seems to me when one item or thing is being mentioned in a sentence as a subject, it follows up with "as follows", but when you are making a sentence with multiple items or things, it is right to use "as follow" with no "s" in the end of the verb. Right or WRONG?
Hello Anon

To my mind, the "as follows" doesn't relate to the content of the following text, but the text itself as a whole, i.e.

1. The two explanations you requested are as (in the text that) follows...

So I would call "as follow" incorrect. But other posters may have other opinions!
