Groom found bride avoiding union! Not acceptable (9)
I believe the answer is:
forbidden
'not acceptable' is the definition.
I can't tell whether this defines the answer.
'groom found bride avoiding union' is the wordplay.
'groom' is an anagram indicator.
'avoiding' is a deletion indicator.
'union' becomes 'u' (common abbreviation as in 'Trades Union Congress').
'found'+'bride'='foundbride'
'foundbride' with 'u' taken away is 'fondbride'.
'fondbride' with letters rearranged gives 'FORBIDDEN'.
Can you help me to learn more?
(Other definitions for forbidden that I've seen before include "not 35 [PERMISSIBLE]" , "Prohibited, taboo" , "Illicit pleasure" , "Disallowed, banned" , "Proscribed" .)
