Get wisdom about current in river (5)
I believe the answer is:
loire
'river' is the definition.
(Loire River is an example)
'get wisdom about current' is the wordplay.
I cannot quite see how this works, but
'about' could be 're' ('re' means regarding or about) and 're' is found in the answer.
'current' could be 'i' (symbol for electric current) and 'i' is present in the answer.
The remaining letters 'lo' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for loire that I've seen before include "River flowing through Tours and Nantes" , "department in France" , "French runner" , "Longest French river" , "banker" .)
