French currency is for animal-loving saint (7)
I believe the answer is:
francis
'saint' is the definition.
(Pope Francis)
'french currency is' is the wordplay.
'french currency' becomes 'franc' (old French currency. I am not sure about the 'french' bit.).
'franc'+'is'='FRANCIS'
'for animal-loving' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for francis that I've seen before include "Man" , "Sir - - Drake" , "Assisi saint" , "My Lady Poverty saint" , "English philosopher, d. 1626 -- Dublin-born painter, d. 1992" .)
