Chap wandering around yonder (6)
I believe the answer is:
rodney
'chap' is the definition.
(man's name)
'wandering around yonder' is the wordplay.
'wandering around' indicates anagramming the letters (I've seen this in other clues).
'yonder' is an anagram of 'RODNEY'.
(Other definitions for rodney that I've seen before include "Del Boy's half-brother in Only Fools and Horses" , "Del Boy's brother" , "Younger brother in Only Fools and Horses" , "English admiral" , "Chap" .)
