Maybe Priam's kin in Troy lay wounded (7)
I believe the answer is:
royalty
'maybe priam's kin' is the definition.
I can't tell whether this defines the answer.
'troy lay wounded' is the wordplay.
'wounded' indicates anagramming the letters.
'troy'+'lay'='troylay'
'troylay' with letters rearranged gives 'ROYALTY'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for royalty that I've seen before include "Sovereigns" , "Payment for the right to use someone else's property" , "Majestic quality" , "Kings, queens, etc" , "Ready for performance" .)
