Revealing runner reeks - tar is involved (8)
I believe the answer is:
streaker
'revealing runner' is the definition.
'streaker' can be an answer for 'runner' (I have seen 'Naked runner' mean 'streaker' so perhaps 'runner' could also mean 'streaker'). I am not sure about the 'revealing' bit.
'reeks tar is involved' is the wordplay.
'is involved' is an anagram indicator (involved can mean confusing or complex).
'reeks'+'tar'='reekstar'
'reekstar' is an anagram of 'STREAKER'.
Can you help me to learn more?
(Other definitions for streaker that I've seen before include "One running naked" , "Naked runner" , "One who runs naughtily nude in public" , "when not having a stitch" , "Someone running naked in a public place" .)
