Bad rules - fancy they'll be around for some time (8)
I believe the answer is:
durables
'they'll be around for some time' is the definition.
I can't tell whether this defines the answer.
'bad rules fancy' is the wordplay.
'fancy' is an anagram indicator.
'bad'+'rules'='badrules'
'badrules' with letters rearranged gives 'DURABLES'.
Can you help me to learn more?
(Other definitions for durables that I've seen before include "Consumer goods that are not destroyed by use" , "Goods likely to long-wearing" .)
