WoodcutterHe plays the guitar the worst in the world????Hi, Woodcutter.
To my ears, we need a clearer designation. "Of all the people in the world, he...." and for the the other similar sentence which Jim said was OK "among my friends" or "of all" etc
CalifJimbut you don't need the "the" nor the complement phrase,If I had to narrow the meaning of the sentence. Is there any option as complement phrase besides using in and of?
