Troublesome ores dug up (4)
I believe the answer is:
sore
'dug up' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives occasionally mean the same thing.
'troublesome ores' is the wordplay.
'troublesome' indicates an anagram.
'ores' with letters rearranged gives 'SORE'.
Can you help me to learn more?
(Other definitions for sore that I've seen before include "Painful or tender" , "Painful spot" , "Rose (anag.)" , "Eros (anag.)" , "Painful, or the source of pain" .)
