Would tea production be forbidden (8)
I believe the answer is:
outlawed
'forbidden' is the definition.
(outlawing is a kind of forbidding)
'would tea production' is the wordplay.
'production' indicates anagramming the letters.
'would'+'tea'='wouldtea'
'wouldtea' is an anagram of 'OUTLAWED'.
'be' is the link.
(Other definitions for outlawed that I've seen before include "proscribed" , "banned" .)
