Returned free packaging from Amazon in worst moment (5)
I believe the answer is:
nadir
'amazon in worst moment' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'returned free packaging' is the wordplay.
'returned' is a reversal indicator.
'free' becomes 'rid' (to be free of something is to be rid of it).
'packaging' becomes 'an' (I am not sure about this - if you are sure you should believe this answer much more).
'rid'+'an'='ridan'
'ridan' reversed gives 'NADIR'.
'from' is the link.
Can you help me to learn more?
(Other definitions for nadir that I've seen before include "pits" , "Lowest point, or time of deepest depression." , "Rock bottom" , "Low spot" , "most unsuccessful point" .)
