Tissue transplant, hard work (5)
I believe the answer is:
graft
This could be a double definition.
'tissue transplant' is the first definition.
'graft' can be an answer for 'transplant' (I have seen 'Surgical transplant ' mean 'graft' so perhaps 'transplant' could also mean 'graft'). I am not sure about the 'tissue' bit.
'hard work' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for graft that I've seen before include "Hard work; corruption" , "Shoot; hard work" , "Transfer of tissue - hard work!" , "Means of propagation - hard work?" , "Slip" .)
