Make certain (6)

I think it could be either:

ensure

assure

'make certain' is the definition.
(synonyms)

This is all the clue.

(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 Wall Street Journal, the Penny Press, The Times, the USA Today, The Star Tribune, The New York Times, The Independent, the Sydney Morning Herald, The Mirror, the Newsday, The Telegraph and The Guardian.
