Car accident involving awful git is heart-rending (6)
I believe the answer is:
tragic
'heart-rending' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tragic that I've seen before include "Deeply distressing" , "Disastrous, desperately sad" , "Very sad; Schubert's 4th symphony nickname" , "Awful" , "Shocking" .)
