A little study in N + N compounds in English, their great utility and versatility (they pack a lot of content into two-word expressions), and their consequent massive potential ambiguity (so that divining the intended meaning can require vast amounts of background knowledge and appreciating details of the context in which the compound is used). You can have (great) brevity, or you can have (great) clarity, but you can’t have both at once.
From the world of commerce, the compound dog spot (which many of us will not have encountered before, or will take to be a reference to the coat pattern of Dalmatian dogs). From the comic strips, two compounds that have conventional interpretations but can also be understood in fresh and unconventional ways: from One Big Happy, dancing school; from Bizarro, cowboy.
