Mean aspect shown by the left in this country (8)
I believe the answer is:
nearside
'by the left in this country' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'mean aspect' is the wordplay.
'mean' becomes 'near' (both can mean miserly).
'aspect' becomes 'side' (side is a kind of aspect).
'near'+'side'='NEARSIDE'
'shown' is the link.
Can you help me to learn more?
(Other definitions for nearside that I've seen before include "Part of car closest to kerb" , "left by kerb?" , "passenger should alight here" , "Part of vehicle closest to the kerb" , "Vehicle's left (in Britain)" .)
