Untidy ruin flattened when clearing the West End (11)
I believe the answer is:
dishevelled
'untidy' is the definition.
(similar in meaning)
'ruin flattened when clearing the west end' is the wordplay.
I cannot quite understand how this works, but
'ruin' could be 'dish' (I've seen this before) and 'dish' is present in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dishevelled that I've seen before include "ill-groomed" , "Rumpled" , "(Of hair, clothes) untidy" , "having a bad hair day?" , "Tousled" .)
