Arranged alphabetically by relevant word, this book contains some interesting idioms. Some of the idioms have a historical or cultural basis, but this isn't explained, so the curious student would have to follow up in a heavier and more expensive reference work--for example the big "Wahrig" German-to-German unilingual dictionary. For example, "German Idioms" lists "nach Adam Riese" 'according to Adam Riese' as an idiom meaning "exactly" (i.e., as when you're confident you've added a column of figures correctly), but doesn't say who A.R. was; the big Wahrig does this, however briefly. The same goes for "nullachtfuenfzehn" (meaning "no great shakes," Wahrig explains it comes from the standard dimensions of an ordinary German apartment). However, "Lieschen Mueller" is in the idioms book but not in Wahrig. So, I'd say the idioms book is good as a scholarly provocation but not as a scholarly fulfillment; but for that reason alone it's good value for the money and should be amusing for the advanced student of German.
