Kind of grass to spoil the sheep? (6)
I believe the answer is:
marram
'kind of grass' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'spoil the sheep?' is the wordplay.
'spoil' becomes 'mar' (synonyms).
'the sheep?' becomes 'ram' (male sheep).
'mar'+'ram'='MARRAM'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for marram that I've seen before include "Coarse grass on sandy beaches" , "Grass of the seaside" , "Sea grass" .)
