Agency upsets that woman consumed by retirement plan with butterflies in her stomach (12)
I believe the answer is:
apprehension
'agency upsets that woman consumed by retirement plan with butterflies' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'her stomach' is the wordplay.
I cannot quite see how this works, but
an anagram of 'her' is 'reh' which is located in the answer.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for apprehension that I've seen before include "Fear" , "Anxious anticipation; understanding" , "Trepidation" , "Arrest -- dread" , "The catching" .)
