A spin out in this? (4)
I believe the answer is:
auto
'this?' is the definition.
The definition suggests a singular noun which matches the answer.
'a spin out' is the wordplay.
'spin' indicates anagramming the letters.
'out' anagrammed gives 'uto'.
'a'+'uto'='AUTO'
'in' acts as a link.
(Other definitions for auto that I've seen before include "Car (mostly US)" , "Prefix denoting by or of the same person or thing" , "Drama" , "Car, in short" , "Car (chiefly in US)" .)
