Settle the will (7)

I believe the answer is:

resolve

This clue is a double definition.

'settle' is the first definition.
(synonyms)

'the will' is the second definition.
(thesaurus)

(Other definitions for resolve that I've seen before include "break up" , "Sort out (a problem)" , "Decide; firm determination" , "Firmly decide" , "Willpower" .)

I've seen this clue in The Guardian, The Telegraph and The Globe and Mail.
