Hire purchase? Nay, in no degree! (5-5)
I believe the answer is:
never-never
This clue might be a double definition.
'hire purchase?' is the first definition.
(thesaurus)
'nay in no degree' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for never-never that I've seen before include "Hire-purchase" , "Easy terms" , "credit facility" .)
