Time to interrupt soothsayer providing guidance (5)
I believe the answer is:
steer
'guidance' is the definition.
(steer is a kind of guidance)
'time to interrupt soothsayer' is the wordplay.
'time' becomes 't'.
'to interrupt' means one lot of letters goes inside another.
'soothsayer' becomes 'seer' (I've seen this before).
't' placed inside 'seer' is 'STEER'.
'providing' acts as a link.
(Other definitions for steer that I've seen before include "Direct; young ox" , "piece of advice" , "Con" , "Control movement" , "give guidance" .)
