Inappropriate conviction concerning two criminals smuggling passport? (14)
I believe the answer is:
overconfidence
'two criminals smuggling passport?' is the definition.
I can't tell whether this defines the answer.
'inappropriate conviction' is the wordplay.
'inappropriate' becomes 'over' (I can't explain this - if you can you should believe this answer much more).
'conviction' becomes 'confidence' (I've seen this before).
'over'+'confidence'='OVERCONFIDENCE'
'concerning' is the link.
Can you help me to learn more?
(Other definitions for overconfidence that I've seen before include "Excessive self-assurance" , "An excess of self-assurance" .)
