Worthiness of home ritual (5)
I believe the answer is:
merit
'worthiness' is the definition.
(merit is a kind of worthiness)
'of home ritual' is the wordplay.
'of' says the answer is hidden in the clue.
'MERIT' is hidden within 'home ritual'.
(Other definitions for merit that I've seen before include "Value" , "of a high order?" , "Good point or quality" , "Excellence, worth" , "Rate" .)
