Alda or Arkin (4)
I believe the answer is:
alan
<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">alda</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >'<span class="explanation-format__original">arkin</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ ></span>
(Other definitions for alan that I've seen before include "-- Sugar, British entrepreneur" , "Sir -- Sugar (The Apprentice)" , "- Bennett, English actor, dramatist, writer" , "English historian/poet" , "A.A. Milne's first name" .)
