Flier in inevitable ascent (3)
I believe the answer is:
bat
'flier in inevitable ascent' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for bat that I've seen before include "The cricketer wields it" , "Small flying mammal - like 11 Across" , "Cricket implement or flying mammal" , "Pipistrelle" , "Wooden implement for cricket" .)
