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 other meanings when used apart from 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.

why is this wrong
bourbon
whiskey by bourbon street/county recipe
not exactly wrong, it's just that nobody ever thinks of poor french kings

there are many other breakers, e.g. waves, or in CB radio, break dancer. It's easy to run into ambiguity.

it's shorthand for both „pharmaceutical drug“ and „psychoactive drug“, and in many cases it's hard to decide which one was meant.

ISO is the international standards organization, not a file extension. Many don't even know this, they say eye ass owe and mean a file.
chef

The word simply means chief. Saying that chef automatically means a cook is an actual insult to all other chiefs in francophone countries who are not cooks. Like chef de police.

rice pilaf
pilaf
Because, in history, there were a few cases when pilaf was made of wheat. So state million times that this is not the case.

television
television set
Same word is used for television as a system, and sometimes for a television station. That's confusing.
