Nothing to fasten? That's what you think! (7)

Ross

I believe the answer is:

opinion

I'm a little stuck... Click here to teach me more about this clue!

'that's what you think' is the definition.
(I've seen this in another clue)

'nothing to fasten?' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'to fasten?' becomes 'pinion' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'o'+'pinion'='OPINION'

Can you help me to learn more?

(Other definitions for opinion that I've seen before include "Estimation" , "Conviction - point of view" , "View, barrister's advice" , "Personal belief or judgment" , "Assessment" .)

I've seen this clue in The Globe and Mail and The Irish News.
