Hardly sending ton back (3)
I believe the answer is:
not
'hardly' is the definition.
(I've seen this in another clue)
'sending ton back' is the wordplay.
'ton' can be anagrammed to 'NOT'.
However, I'm not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for not that I've seen before include "Having close-cut hair" , "logically, operation needed" , "Type of logic gate" , "Negation of what follows" , "A negative word" .)
