I've always understood that you can order the words
every (or similar words) in the following two ways to convey distinct logical meanings.
- Every human is not a man. There is no human being who is a man.
- Not every human is a man. There are human beings who are not men.
Being a non-native speaker, I learn most of my English by reading things on the internet. The thing is that I almost never see people doing it this way and this made me question my understanding.
For example, a comment on another Stack Exchange website reads:
Everything on DOS is not plain-text!
To my understanding, this sentence means that there is nothing on DOS that is plain-text, but it is clear to me that the author of the message intended a different meaning. I would correct this sentence to:
Not everything on DOS is plain-text!
Am I correct and is this mistake very commonly made or do I have a fundamental misunderstanding of this sentence structure?
