Swimmer with tattoos above suspicion (7)
I believe the answer is:
inkling
'suspicion' is the definition.
(an inkling is a suspicion or idea)
'swimmer with tattoos above' is the wordplay.
'swimmer' becomes 'ling' (ling is a type of fish).
'with' is a charade indicator (letters next to each other).
'tattoos above' becomes 'ink' (I've seen this in another clue. I am not sure about the 'above' bit.).
'ling' put after 'ink' is 'INKLING'.
Can you help me to learn more?
(Other definitions for inkling that I've seen before include "Suspicion, hunch" , "Thought" , "Slightest idea" , "Linking with suspicion or hint" , "Slight hint or suspicion" .)
