I have an image of a type of hat in the real world, but I don't know what it's called. Where can I ask what the name for this kind of hat is?
My first thought was the single-word-requests tag on English Language and Usage, but according to that tag's info:
To ensure your question is not closed as off-topic, please be specific about the intended use of the word. YOU MUST INCLUDE A SAMPLE SENTENCE DEMONSTRATING HOW THE WORD WOULD BE USED.
which means that it has to be about a word, not about "what kind of object is this?".
