It’s loud, OK, and gives you a shock? (6)
I believe the answer is:
fright
'a shock?' is the definition.
(thesaurus)
'it's loud ok' is the wordplay.
'it's loud' becomes 'f' (A musical term).
'ok' becomes 'right' (I've seen this in other clues).
'f'+'right'='FRIGHT'
'and gives you' 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 fright that I've seen before include "Shock, intense fear" , "Sudden exposure to fear" , "Alarming event" , "Panic" , "Horror" .)
