Swimmer good leading another two? (8)
I believe the answer is:
grayling
'swimmer' is the definition.
(grayling is a type of fish)
'good leading another two?' is the wordplay.
I cannot really understand how this works, but
'good' could be 'g' (abbreviation) and 'g' is found in the answer.
'leading' could be 'in' (in government) and 'in' is found within the answer.
'another' could be 'r' (I've seen this in other clues) and 'r' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for grayling that I've seen before include "Catch" , "Salmonoid fish" , "Fish - philosopher" , "Fish of the salmon family" , "Butterfly" .)
