Receive deliveries of book and wait for periodical appearance (3)
I believe the answer is:
bat
'periodical appearance' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'receive deliveries of book and wait' is the wordplay.
I cannot really see how this works, but
'book' could be 'b' (abbreviation for book) and 'b' is present in the answer.
The remaining letters 'at' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for bat that I've seen before include "Small flying mammal, may be vampire" , "Pipistrelle" , "A mammal; a club" , "Wooden implement for cricket" , "Small flying mammal - like 11 Across" .)
