Wine tipped over on last word, needing Tippex? (7)
I believe the answer is:
'tippex?' is the definition.
I can't tell whether this defines the answer.
'wine tipped over on last word' is the wordplay.
'wine' becomes 'red' (red wine is an example).
'tipped over' is a reversal indicator.
'on' means one lot of letters go next to another.
'last word' becomes 'amen' (I've seen this before).
'red' back-to-front is 'der'.
'der' put after 'amen' is 'AMENDER'.
'needing' acts as a link.
Can you help me to learn more?
(Other definitions for amender that I've seen before include "Editor" , "agent of change" .)
