Make certain (6)

Ross

I think it could be either:

ensure

assure

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">make certain</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is all the clue.<br/ ></span>

(Other definitions for ensure that I've seen before include "Make certain, clinch" , "Make certain for the future" , "Make certain or safe" , "warrant" , "Make certain that (something occurs)" .)

I've seen this clue in the LA Times, The Independent, the Sydney Morning Herald, the USA Today, The New York Times, The Wall Street Journal, The Star Tribune, The Irish Times, the Penny Press, The Guardian, The Times, The Mirror, the Newsday and The Telegraph.
