My French king is brother (4)

Ross

I believe the answer is:

monk

'is brother' is the definition.
(I've seen this before)

'my french king' is the wordplay.
'my french' becomes 'mon'.
'king' becomes 'k'.
'mon'+'k'='MONK'

(Other definitions for monk that I've seen before include "Tonsured person" , "Friar" , "Setter" , "One vowed" , "Man in a religious order" .)

I've seen this clue in The Mirror.
