Protected from shock but still broken-hearted (7)
I believe the answer is:
earthed
'protected from shock' is the definition.
(I've seen this before)
'broken-hearted' is the wordplay.
'broken' is an anagram indicator.
'hearted' is an anagram of 'EARTHED'.
'but still' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for earthed that I've seen before include "attached to the ground" , "protected from shock" , "grounded" .)
