Check perennial for new life (13)
I believe the answer is:
reincarnation
'new life' is the definition.
(I've seen this before)
'check perennial' is the wordplay.
I cannot really understand how this works, but
'check' could be 'rein' (both can mean to control or limit) and 'rein' is located in the answer.
The remaining letters 'carnation' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for reincarnation that I've seen before include "Rebirth in a new body" , "new life" , "Soul's rebirth in another body" , "getting new body" , "Embodiment of a soul in a new form after death" .)
