She’s pale, really going backwards — this being evident? (7)
I believe the answer is:
relapse
'going backwards this being evident?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'she's pale really' is the wordplay.
'RELAPSE' is hidden back-to-front in amongst the letters.
But, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for relapse that I've seen before include "Fall back into former state" , "Regress, fall back" , "Get worse again" , "Fall back into former condition, being pleaser" , "New downturn in health" .)
