After shuts, have a frightening experience (5,5)
I believe the answer is:
close shave
'a frightening experience' is the definition.
The definition suggests a singular noun which matches the answer.
'after shuts have' is the wordplay.
'after' says to put letters next to each other.
'shuts' becomes 'closes' ('close' can be a synonym of 'shut').
'closes' next to 'have' is 'CLOSE SHAVE'.
Can you help me to learn more?
(Other definitions for close shave that I've seen before include "Danger narrowly averted" , "resulting in barefaced cheek?" , "Chases vole (anag.)" , "Near thing" , "Narrow escape from disaster" .)
