Whack with a rolled up Times (5)
I believe the answer is:
smite
'whack' is the definition.
(I've seen this before)
'up times' is the wordplay.
'up' is an anagram indicator (letters get chucked up).
'times' with letters rearranged gives 'SMITE'.
'with a rolled' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for smite that I've seen before include "Whack" , "Strike firmly" , "Strike heavily" , "Hit hard in olden times" , "Strike with a firm blow" .)
