Smart aleck caught by detective casing bar (6,4)
I believe the answer is:
clever dick
'smart aleck' is the definition.
Both the answer and definition are singular nouns.
Maybe there's an association between them I don't understand?
'caught by detective casing bar' is the wordplay.
'caught by' becomes 'c' (cricket abbreviation. I am not sure about the 'by' bit.).
'detective' becomes 'dick' (informal term for a detective).
'casing' is an insertion indicator (I've seen this in other clues).
'bar' becomes 'lever' (lever is a kind of bar).
'c'+'dick'='cdick'
'cdick' going around 'lever' is 'CLEVER DICK'.
Can you help me to learn more?
(Other definitions for clever dick that I've seen before include "Wise guy" , "The one with all the answers" , "Know-all" .)
