Crossword Genius

Swimmer feeling about (3)

Ross

I believe the answer is:

eel

'swimmer' is the definition.
(eel is a type of fish)

'feeling about' is the wordplay.
'about' indicates a hidden word (the clue goes around or about the answer).
'EEL' is hidden within 'feeling'.

(Other definitions for eel that I've seen before include "Serpentine fish" , "Large elver" , "elusive person" , "A sea snake" , "Long thin fish" .)

I've seen this clue in The Mirror.
