Who’s primarily from religious institution and robed (5)
I believe the answer is:
friar
'who's' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'primarily from religious institution and robed' is the wordplay.
'primarily' says to take the initial letters.
The first letters of 'from religious institution and robed' is 'FRIAR'.
Can you help me to learn more?
(Other definitions for friar that I've seen before include "Male member of a mendicant religious order" , "Father" , "Eg, a Dominican" , "Eg, a Franciscan" , "Mendicant priest" .)
