Royal with ring, second-hand, being woken up (6)
I believe the answer is:
roused
'being woken up' is the definition.
(I've seen this before)
'royal with ring second-hand' is the wordplay.
'royal' becomes 'r' (common abbreviation e.g. RM - Royal Marine).
'with' is a charade indicator (letters next to each other).
'ring' becomes 'O' (letter resembling a ring).
'second hand' becomes 'used' (second hand can mean previously owned or used).
'r'+'o'+'used'='ROUSED'
(Other definitions for roused that I've seen before include "Made to waken or to become excited" , "Stimulated" , "Galvanized" , "Woken up or angered" , "Soured (anag.)" .)
