Badly grown? (5)
I believe the answer is:
wrong
'badly' is the definition.
(thesaurus)
'grown?' is the wordplay.
'grown' anagrams to 'WRONG'.
However, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for wrong that I've seen before include "Erronious" , "Erroneous" , "Incorrect - sinful" , "bad" , "Treat unjustly" .)
