Hides from king protected by religious ritual (5)
I believe the answer is:
masks
'hides' is the definition.
(I've seen this in another clue)
'king protected by religious ritual' is the wordplay.
'king' becomes 'K' (abbreviation for king in chess).
'protected by' means one lot of letters goes inside another (inserted letters are held or protected).
'religious ritual' becomes 'mass' (I've seen this in another clue).
'k' placed within 'mass' is 'MASKS'.
'from' acts as a link.
(Other definitions for masks that I've seen before include "Coverings to conceal the face" , "Hides, disguises" .)
