Give a new name to (7)
I believe the answer is:
retitle
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">give a new name to</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for retitle that I've seen before include "Name afresh" , "Give a new name to" , "Give a different name to (a book)" , "name differently" , "Call again on" .)
