New pine kitchen? An awful bore (4,2,3,4)
I believe the answer is:
pain in the neck
'bore' is the definition.
(thesaurus)
'new pine kitchen? an awful' is the wordplay.
'new' becomes 'n'.
'an' becomes 'a'.
'awful' is an anagram indicator.
'n'+'pine'+'kitchen'+'a'='npinekitchena'
'npinekitchena' with letters rearranged gives 'PAIN IN THE NECK'.
(Other definitions for pain in the neck that I've seen before include "Headache" , "Bothersome annoying person" , "Really annoying person" , "Troublesome person or thing" , "Torticollis" .)
