Hi Mike,
Main Entry: 1spe·cif·ic
Pronunciation: spi-'si-fik
Function: adjective
Etymology: Late Latin specificus, from Latin species
1 a : constituting or falling into a specifiable category b : sharing or being those properties of something that allow it to be referred to a particular category
I believe that naming boat make or sail maker is contituting falling into a specifiable category, so doing so is a violation of the rules. Am I missing something here?
It really is a good topic, though!
