This was a real stinker. Not in any dictionary I could find, English or French. But I found several
sites that mentioned it. Many were names of reataurants. One was a magazine "L'Assiette de la Beurre"
A couple were about tables for computation. An "assiete de calcul" was a hand held calculator. Finally
I found a couple sites that showed pictures of"Assiettes" that were plainly dinner plates.
I'm still annoyed.
