Fruit (slang) fruit" (and rarely "old tin of fruit") to the 1920s in Britain possibly deriving from the phrase "fruit of the womb". In the United States, however, both "fruit" and "fruitcake" are seen as negative with fruitcake likely originating from "nutty as a fruitcake" (a crazy person). A costermonger was a street seller of fruit and vegetables. The term, which derived from the words "costard" (a type of apple) and "monger", i.e. "seller", came to be particularly associated with the "barrow boys" of London who would sell their produce from a wheelbarrow or wheeled market stall. Costermongers have existed in London
Abelian variety of CM-type manipulate analytic functions of several complex variables. The formal definition is that the tensor product of End("A") with the rational number field Q, should contain a commutative subring of dimension 2"d" over Q. When "d" = 1 this can only be a quadratic field, and one recovers the cases where End("A") is an order in an imaginary quadratic field. For "d" > 1 there are comparable cases for CM-fields, the complex quadratic extensions of totally real fields. There are other cases that reflect that "A" may not be a simple abelian variety (it might be a cartesian product of elliptic
