Send a letter to a total wreck (5-3)
I believe the answer is:
write-off
This might be a double definition.
'send a letter' is the first definition.
(I've seen this before)
'total wreck' is the second definition.
'write off' can be an answer for 'wreck' (as in writing off a car). I'm not sure about the 'total' bit.
'to a' is the link.
Can you help me to learn more?
(Other definitions for write-off that I've seen before include "Article beyond repair" , "Car too costly to repair" , "Cancel like bad debt" , "Send a letter - cancel a debt" , "Destroy (car)" .)
