<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not frank</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for evasive that I've seen before include "Shifty, hard to pin down" , "Trying to avoid commitment" , "Devious" , "Prevaricatory" , "Tending to avoid commitment" .)
