for all the world
In all respects, precisely, as in She looked for all the world like Greta Garbo. [Late 1300s]
Also, not for the world. Not for anything, not at any price. For example, I wouldn't give up chocolate for all the world, or Not for the world would I reveal your secret. This hyperbolic expression is generally part of a negative statement. [First half of 1800s] For a synonym, see not for love or money.
