Sail ruffled ocean initially, then lay back (5)
I believe the answer is:
royal
'sail' is the definition.
(type of sail)
'ruffled ocean initially then lay back' is the wordplay.
'initially' says to take the initial letters.
'then' is a charade indicator (letters next to each other).
'back' says the letters should be written in reverse.
The first letters of 'ruffled ocean' is 'ro'.
'lay' written backwards gives 'yal'.
'ro'+'yal'='ROYAL'
(Other definitions for royal that I've seen before include "What we may get used for individual" , "Like Priam" , "Suitable for king or queen" , "Member of ruling family" , "like Alonso" .)
