Strike from account upon reflection (3)
I believe the answer is:
bat
'strike' is the definition.
(thesaurus)
'account upon reflection' is the wordplay.
'account' becomes 'tab' (tab is a kind of account).
'upon reflection' says the letters should be written in reverse.
'tab' back-to-front is 'BAT'.
'from' is the link.
(Other definitions for bat that I've seen before include "Night-flying mammal" , "Nocturnal mouselike mammal" , "Night flier" , "The cricketer wields it" , "Night-flyer" .)
