Leading seamen point to fish (8)
I believe the answer is:
skippers
'leading seamen' is the definition.
'skippers' can be an answer for 'seamen' (skipper is a kind of seaman). I'm unsure of the 'leading' bit.
'point to fish' is the wordplay.
'point' becomes 's' (South).
'to fish' becomes 'kippers' (I've seen this before).
's'+'kippers'='SKIPPERS'
Can you help me to learn more?
(Other definitions for skippers that I've seen before include "Masters" , "Sea captains" , "Captains of ships or sports teams" , "Informal ship captains" , "taking PE?" .)
