Turned off to be amused (8)
I believe the answer is:
diverted
This could be a double definition.
'turned off' is the first definition.
'diverted' can be an answer for 'turned' (diverting is a kind of turning). I'm unsure of the 'off' bit.
'be amused' is the second definition.
(synonyms)
'to' acts as a link.
Can you help me to learn more?
(Other definitions for diverted that I've seen before include "Rechannelled" , "Changed direction, deviated" , "Sent traffic in alternative direction" , "Taken out of oneself" , "Change course and entertained" .)
