Engaged; reserved (6,3)
I believe the answer is:
spoken for
I believe this clue is a double definition.
'engaged' is the first definition.
(I've seen this before)
'reserved' is the second definition.
(I've seen this before)
(Other definitions for spoken for that I've seen before include "Not a single" , "Sold!" , "Unavailable (as a partner)" , "Reserved" , "Romantically attached" .)
