Unfinished cycle in central Pacific atomic site (6)
I believe the answer is:
bikini
'atomic site' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'unfinished cycle in central pacific' is the wordplay.
'unfinished' means to remove the last letter.
'cycle' becomes 'bike' (bike is a kind of cycle).
'central' means to look at the middle letters.
The middle letter of 'pacific' is 'i'.
'bike' with its last letter removed is 'bik'.
'bik'+'in'+'i'='BIKINI'
Can you help me to learn more?
(Other definitions for bikini that I've seen before include "providing little cover for swimmers" , "Small two-piece bathing suit" , "Bathing suit for the atoll?" , "Skimpy two-piece swim wear" , "Beach wear" .)
