Am run ragged in Belgium! (5)
I believe the answer is:
namur
'ragged in belgium' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'am run' is the wordplay.
I cannot quite understand how this works, but
'am' is present in the answer.
an anagram of 'run' is 'nur' which is present in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for namur that I've seen is " Belgian city and province".)
