An expert in current affairs? (11)
I believe the answer is:
electrician
'an expert' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'current affairs?' is the wordplay.
I cannot quite see how this works, but
'current' could be 'electric' (synonyms) and 'electric' is found in the answer.
The remaining letters 'ian' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for electrician that I've seen before include "he might shed light?" , "Installer of mains-powered equipment" , "One wiring house" , "Installer of wiring, etc" , "One who might install mains wiring" .)
