Basically, 'Spanish', 'Greek' or 'Sheikh' (I don't think romance writers know what this word means. Or they're using it exclusively to mean 'man of stature'. I suppose 'old man' or 'Islamic scholar' isn't really as sexy as 'foreign prince').

HEE! Yes!

I am still rather amazed that Harlequin continues its Exotic Ethnicity line, though, like you mention, it's usually for the Spanish, Greeks, "Sheikhs" or Italians only.
