Some rituals have worth (5)
I believe the answer is:
merit
'worth' is the definition.
(I know that merit is a type of worth)
'some rituals have' is the wordplay.
'have' indicates the answer is hidden within the clue.
'MERIT' is hidden in the letters of 'some rituals'.
(Other definitions for merit that I've seen before include "Excellence, desert" , "Earn" , "Value" , "Goodness" , "Advantage" .)
