Monastery's repeated planning application? (10)
I believe the answer is:
chartreuse
'monastery's' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'repeated planning application?' is the wordplay.
I cannot quite see how this works, but
'application?' could be 'use' (application is a kind of use) and 'use' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for chartreuse that I've seen before include "Carthusian liqueur" , "Green-yellow liqueur" , "green liquid" , "drink" , "Pale green-yellow colour" .)
