Windows once put in Kerry's place, perish (6)
I believe the answer is:
expire
'perish' is the definition.
(synonyms)
'windows once put in kerry's place' is the wordplay.
I cannot really see how this works, but
'once' could be 'ex' and 'ex' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for expire that I've seen before include "Run out, exhale" , "Breathe out or pass away" , "Die or lapse" , "Breathe out or run out" , "Die or terminate" .)
