A man is capable of establishing a religious order (10)
I believe the answer is:
franciscan
'establishing a religious order' is the definition.
I can't tell whether this defines the answer.
'a man is capable' is the wordplay.
'a man' becomes 'francis' (I've seen this before).
'is capable' becomes 'can' (I've seen this in another clue).
'francis'+'can'='FRANCISCAN'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for franciscan that I've seen before include "Grey Friar" , "one's in order" , "The sort of friar" , "One under orders" , "Type of monk" .)
