Rest in home, rest outside to be flexible (9)
I believe the answer is:
resilient
'flexible' is the definition.
(thesaurus)
'rest in home rest outside' is the wordplay.
I cannot quite understand how this works, but
'rest' could be 'lie' (lying is a kind of resting) and 'lie' is located in the answer.
'in' is within the answer.
'home' could be 'rest' ('rest home' can be a synonym of 'home') and 'rest' is found in the remaining letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for resilient that I've seen before include "Elastic" , "recovering easily from shock" , "Tough" , "Rebounding from impact" , "Flexible" .)
