Frozen food in lounge goes out of date (7)
I believe the answer is:
lollies
'frozen food in lounge goes out of date' is the definition.
I can't judge whether this definition defines the answer.
'in lounge goes out of date' is the wordplay.
'in lounge' becomes 'loll' (both can mean to sit in a relaxed way. I am not sure about the 'in' bit.).
'goes' becomes 'dies' ('die' can be a synonym of 'go').
'out of' is a deletion indicator.
'date' becomes 'd' (abbreviation e.g. dob - date of birth).
'dies' with 'd' taken away is 'ies'.
'loll'+'ies'='LOLLIES'
Can you help me to learn more?
(Other definitions for lollies that I've seen before include "Refrigerated sweets" , "Licked sweets" , "Iced sweets" , "Sweets (colloq.)" .)
