One is enough

What is this?
I don't know what's the proper name for this category of words. The cases when one word from a phrase is taken out to mean the whole phrase, despite it having several uses outside of the phrase.For symmetry, I've included a few oddly specific phrases, where an extra word is commonly added to denote the very important difference between the millions of instances of the common variant and the couple of exceptions.
