Flier with a hang-up? (3)
I believe the answer is:
bat
'hang-up?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'flier with a' is the wordplay.
'flier' becomes 'bt' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' indicates putting letters inside.
'bt' placed around 'a' is 'BAT'.
Can you help me to learn more?
(Other definitions for bat that I've seen before include "Small flying mammal - like 11 Across" , "once wielded by 60 [GREIG]" , "Cricket, table-tennis and baseball implement" , "Night-flying mammal" , "Pipistrelle" .)
