Half of tree, flower and cherry stolen (9)
I believe the answer is:
trousered
'stolen' is the definition.
Both the answer and definition are adjectives. Maybe you can see an association between them that I can't see?
'half of tree flower and cherry' is the wordplay.
'half of' suggests halving the letters.
'flower' becomes 'ouse' (Yorkshire river).
'and' means one lot of letters go next to another.
'cherry' becomes 'red' (synonyms).
'tree' halved is 'tr'.
'tr'+'ouse'+'red'='TROUSERED'
Can you help me to learn more?
(Other definitions for trousered that I've seen before include "in jeans?" , "Drunk -- stole" , "pocketed cash?" , "Took for oneself" , "Decently attired" .)
