Put me up at last to make corrections (5)
I believe the answer is:
emend
'make corrections' is the definition.
(I've seen this before)
'put me up at last' is the wordplay.
I cannot really see how this works, but
'me' is found in the answer.
'last' could be 'end' (I've seen this in another clue) and 'end' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for emend that I've seen before include "do editorial work" , "change" , "Correct; edit" , "Correct/revise (a text)" , "Improve by editing" .)
