Possibly sent half a mile to rest in comfort (6)
I believe the answer is:
nestle
'rest in comfort' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'possibly sent half a mile' is the wordplay.
'possibly' is an anagram indicator.
'half a' indicates taking half.
'mile' cut in half is 'le'.
'sent' is an anagram of 'nest'.
'nest'+'le'='NESTLE'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for nestle that I've seen before include "Cuddle into soft place" , "Snuggle or curl up" , "Cuddle, curl up" , "Chocolate maker" , "Cuddle closely" .)
