Method to limit volume of the sea, perhaps (4)
I believe the answer is:
wavy
'the sea perhaps' is the definition.
I can't judge whether this definition defines the answer.
'method to limit volume' is the wordplay.
'method' becomes 'way' (way of doing something).
'to limit' is an insertion indicator.
'volume' becomes 'v' (abbreviation for volume in book titles).
'way' placed around 'v' is 'WAVY'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for wavy that I've seen before include "full of bends" , "Rippled" , "Undulating" , "Curly (hair)" , "Sinuous" .)
