With a heart transplant, be about to show life (7)
I believe the answer is:
breathe
'to show life' is the definition.
I can't tell whether this definition defines the answer.
'with a heart transplant be' is the wordplay.
'with' means one lot of letters goes inside another.
'transplant' indicates anagramming the letters.
'heart' is an anagram of 'reath'.
'reath' placed into 'be' is 'BREATHE'.
'about' is the link.
Can you help me to learn more?
(Other definitions for breathe that I've seen before include "Respire - inspire - expire" , "Take into mouth" , "Take air in and out of the lungs" , "Take inspiration" , "Inhale and exhale" .)
