Invests a man of the cloth with the origin of fire and ice (6)
I believe the answer is:
frocks
'invests a man of the cloth with' is the definition.
I can't tell whether this definition defines the answer.
'origin of fire and ice' is the wordplay.
'origin of' suggests taking the first letters.
'and' means one lot of letters go next to another.
'ice' becomes 'rocks' (both can informally mean diamonds).
The initial letter of 'fire' is 'f'.
'f'+'rocks'='FROCKS'
'the' is the link.
Can you help me to learn more?
(Other definitions for frocks that I've seen before include "Dresses" , "party attire?" .)
