Wayward monarch right to be seen by social worker (6)
I believe the answer is:
errant
'wayward' is the definition.
(I've seen this before)
'monarch right to be seen by social worker' is the wordplay.
'monarch' becomes 'er' (abbreviation for Elizabeth Regina, British Queen).
'right' becomes 'r' (common abbreviation).
'to be seen by' means one lot of letters go next to another.
'social worker' becomes 'ant' (I've seen this before).
'er'+'r'+'ant'='ERRANT'
(Other definitions for errant that I've seen before include "Kind of knight who once travelled for adventure" , "Straying; knight" , "Nomadic" , "Wrong" , "Quixotic" .)
