Wicked old chamber ten destroyed (9)
I believe the answer is:
excellent
'wicked' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'old chamber ten destroyed' is the wordplay.
'old' becomes 'ex' (prefix meaning former or onetime).
'chamber' becomes 'cell' (I've seen this before).
'destroyed' indicates an anagram.
'ten' with letters rearranged gives 'ent'.
'ex'+'cell'+'ent'='EXCELLENT'
Can you help me to learn more?
(Other definitions for excellent that I've seen before include "Fine" , "Outstanding, very good" , "Admirable, first-rate" , "brilliant" , "Superior, of the highest quality" .)
