what's the difference between AS and LIKE? When Can I use it ?
I like to know when Can I use LIKE or AS and why?

Question

Answer

It is used when you want to compare. Like is not followed by verb but as is. You are doing as I do. You are like me.

Answer

A comparison using like or as is called a simile.
here;'s an interesting page about similes and metaphors (which also compare things).

Here's another on similes alone:
