Fish seen below by little Florence (8)
I believe the answer is:
flounder
'fish' is the definition.
(flounder is a kind of fish)
'below by little florence' is the wordplay.
'below' becomes 'under' (synonyms).
'by' is a charade indicator (letters next to each other).
'little florence' becomes 'flo' (I am not sure about the 'little' bit.).
'under' after 'flo' is 'FLOUNDER'.
'seen' acts as a link.
Can you help me to learn more?
(Other definitions for flounder that I've seen before include "thrash around wildly" , "Flatfish - behave awkwardly" , "Small flatfish" , "small swimmer" , "Thrash about helplessly around the fish" .)
