Type of word puzzle (7)
I believe the answer is:
anagram
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">type of word puzzle</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for anagram that I've seen before include "Word created from other word" , "Letter puzzle" , "Argue the point" , "Jumbling of letters" , "Gelding can be niggled by this" .)
