Change one's story? (4)
I believe the answer is:
edit
'change one's story?' is the definition.
(I've seen this in another clue)
'one's story?' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
The remaining letters 'edt' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for edit that I've seen before include "Revise text" , "Prepare text for publication" , "Be in charge (of paper)" , "work on newspaper?" , "Make textual changes" .)
