Warning to saint in woodland region (6)
I believe the answer is:
forest
'woodland region' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'warning to saint' is the wordplay.
'warning' becomes 'fore' (shouted in golf).
'to saint' becomes 'st' (abbreviation).
'fore'+'st'='FOREST'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for forest that I've seen before include "eg Sherwood" , "See 15" , "Tree-covered area" , "that has branches everywhere" , "Wooded region" .)
