Views the second of four gears (8)
I believe the answer is:
opinions
'views the second' is the definition.
'opinions' can be an answer for 'views' (I've seen this before). I'm not sure about the 'the second' bit.
'of four gears' is the wordplay.
'of' becomes 'o'.
'four gears' becomes 'pinions' (pinion is a kind of gear. I am not sure about the 'four' bit.**).
'o'+'pinions'='OPINIONS'
Can you help me to learn more?
(Other definitions for opinions that I've seen before include "Personal views" , "Macbeth bought golden ones" , "Personal beliefs or judgments" , "'Beliefs, convictions (8)'" , "ideas" .)
