Monastic custom? (5)
I believe the answer is:
habit
This clue might be a double definition.
'monastic' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'custom?' is the second definition.
(I know that habit is a type of custom)
Can you help me to learn more?
(Other definitions for habit that I've seen before include "It's second nature" , "Ingrained behaviour" , "nun gets into" , "Propensity" , "Monk's garb" .)
