The richer villagers hoard this herb (7)
I believe the answer is:
chervil
'this herb' is the definition.
(chervil is a kind of herb)
'the richer villagers hoard' is the wordplay.
'CHERVIL' is hidden in amongst the letters.
However, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for chervil that I've seen before include "Herb, relative of parsley" , "Parsley relative with aromatic leaves" , "The green stuff" , "Cicely's relation" , "Herb of the parsley family" .)
