Without guile (7)
I believe the answer is:
artless
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">without guile</span>' is the definition.<br/ ><span class="explanation-format__explanation">('guile' can be 'art' (I've seen this in another clue) so maybe 'without guile' can be ''artless')</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for artless that I've seen before include "Natural like slaters" , "Without pretension" , "Clumsy and uncaring" , "Nave" , "Ingenuous" .)
