PM Heath reflected, around his home, on English reconciliation (7)
I believe the answer is:
detente
'reconciliation' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for detente that I've seen before include "Easing of international tension" , "Easing of hostility between countries" , "Thaw in relations" , "Slackening of tension" , "Easing of strained relations" .)
