Cuts in middle of Greece produce blackouts (7)
I believe the answer is:
eclipse
'produce blackouts' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'cuts in middle of greece' is the wordplay.
'cuts' becomes 'clips' (clip is a kind of cut).
'in' is an insertion indicator.
'middle of' indicates the central letters.
The middle letters of 'greece' are 'ee'.
'clips' inserted into 'ee' is 'ECLIPSE'.
Can you help me to learn more?
(Other definitions for eclipse that I've seen before include "Heavenly phenomenon" , "Obscuring of a heavenly body" , "famous racehorse" , "Cut out" , "When light's dropped" .)
