Correct info on part of Morse alphabet (4)
I believe the answer is:
edit
'correct' is the definition.
(edit can mean to correct or emend)
'info on part of morse alphabet' is the wordplay.
I cannot quite see how this works, but
'part of morse' could be 'dit' ('dit' is part of 'morse') and 'dit' is found in the answer.
A single letter 'e' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
(Other definitions for edit that I've seen before include "Literally, arrange" , "Prepare (material) for publication" , "Ready for publication" , "Prepare text for publication" , "Prepare to publish" .)
