Gutted - one sector struggling? This should stop the rot (8)
I believe the answer is:
creosote
'this should stop the rot' is the definition.
The definition suggests a singular noun which matches the answer.
'gutted one sector struggling?' is the wordplay.
'gutted' says to hollow out the word (remove centre letters) (to gut something is to remove its insides).
'struggling?' indicates an anagram (the letters struggle or wriggle into a new form).
'one' with its centre taken out is 'oe'.
'oe'+'sector'='oesector'
'oesector' with letters rearranged gives 'CREOSOTE'.
Can you help me to learn more?
(Other definitions for creosote that I've seen before include "Fencing gear, perhaps" , "Wood preservative oil" , "Preservative liquid obtained from coal tar" , "Oily liquid for preserving timber" , "Wood treatment" .)
