Word made from the letters of another (7)
I believe the answer is:
anagram
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">word made from the letters of another</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 "pouring the tea?" , "Jumbling of letters" , "Jumble of letters" , "Scramble of letters (to make trestle, perhaps)" , "Word arranged from the letters of another" .)
