Gong that could give you a dizzy head during dinner? (5)
I believe the answer is:
medal
'gong that could give' is the definition.
'medal' can be an answer for 'gong' (gong can mean a prize or medal). I am not certain of the rest of the definition.
'a dizzy head during dinner?' is the wordplay.
'head' suggests taking the first letters.
'during' indicates putting letters inside.
'dinner?' becomes 'meal' (dinner is a meal).
The initial letter of 'dizzy' is 'd'.
'd' inserted within 'meal' is 'MEDAL'.
'you' is the link.
Can you help me to learn more?
(Other definitions for medal that I've seen before include "An award, in slang a gong" , "Olympic award" , "What an Olympic Games winner gets" , "Lamed by award" , "Religious or commemorative award" .)
