Certain to put the question to, by hook or by crook (7)
I believe the answer is:
somehow
'by hook or by crook' is the definition.
(I've seen this before)
'certain to put the question' is the wordplay.
'certain' becomes 'some' ('some' can be a synonym of 'certain').
'to put' is a charade indicator (letters next to each other).
'the question' becomes 'how' (I've seen this in other clues**).
'some'+'how'='SOMEHOW'
'to' is the link.
(Other definitions for somehow that I've seen before include "In a way not yet specified" , "By one means or another" , "For some unspecified reason" , "For an unknown reason; so who, me? (anag.)" , "In an unspecified way" .)
