Remove old volume being talked about (6)
I believe the answer is:
excise
'remove' is the definition.
(I've seen this before)
'old volume being talked about' is the wordplay.
I cannot really see how this works, but
'old' could be 'ex' (prefix meaning former or onetime) and 'ex' is found in the answer.
'about' could be 'c' (abbreviation for circa) and 'c' is found in the answer.
The remaining letters 'ise' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for excise that I've seen before include "Cut out; commodity tax" , "Tax on certain goods and commodities" , "that wretches hatefully collect" , "Expunge the tax?" , "Duty; cut out" .)
