Not so fast - skinhead has the inside story? (8)
I believe the answer is:
slowdown
'not so fast' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'skinhead has the inside story?' is the wordplay.
'skinhead' becomes 's' (head letter of 'skin').
'has' says to put letters next to each other.
'the inside story?' becomes 'lowdown' (I've seen this before).
's'+'lowdown'='SLOWDOWN'
Can you help me to learn more?
(Other definitions for slowdown that I've seen before include "reduction in rate" , "Decline in economic activity" , "Lose velocity" , "reduction in economic growth" , "example of industrial action in US" .)
