Cutter with a rotary action? (7)
I believe the answer is:
chopper
'cutter' is the definition.
(chopper is a kind of cutter)
'a rotary action?' is the wordplay.
I cannot quite see how this works, but
'a' could be 'per' (eg 'one a day' means 'one per day') and 'per' is present in the answer.
'action?' could be 'chop' (chop is a kind of action) and 'chop' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'with' acts as a link.
Can you help me to learn more?
(Other definitions for chopper that I've seen before include "An axe, or a slang helicopter" , "An informal helicopter, or an axe" , "that's used by a lumberjack" , "Small axe" , "Air transport" .)
