Beat Don up? (5)
I believe the answer is:
pound
'beat don up?' is the definition.
I can't tell whether this definition defines the answer.
'beat don up?' is the wordplay.
'beat' indicates anagramming the letters.
'don'+'up'='donup'
'donup' with letters rearranged gives 'POUND'.
Can you help me to learn more?
(Other definitions for pound that I've seen before include "Cars towed to it; hit heavily" , "Where vehicles may be reclaimed" , "PS" , "16 ounces" , "British currency" .)
