It may be checked for drink and meat around midnight (7)
I believe the answer is:
gingham
'it may be checked' is the definition.
The definition suggests a singular noun which matches the answer.
'drink and meat around midnight' is the wordplay.
'drink' becomes 'gin' (gin is an alcoholic drink).
'and' says to put letters next to each other.
'meat' becomes 'ham' (ham is a kind of meat).
'around' is an insertion indicator.
'midnight' becomes 'g' (the middle letter in 'night').
'gin'+'ham'='ginham'
'ginham' enclosing 'g' is 'GINGHAM'.
'for' is the link.
Can you help me to learn more?
