Meander amongst biggest rollers (6)
I believe the answer is:
stroll
'meander' is the definition.
(I've seen this in another clue)
'amongst biggest rollers' is the wordplay.
'amongst' indicates a hidden word.
'STROLL' is hidden in the letters of 'biggest rollers'.
(Other definitions for stroll that I've seen before include "walk in a leisurely manner" , "Amble or ramble" , "Meander" , "A casual or leisurely walk" , "Promenade" .)
