Shoots a prude when there are saints around (6)
I believe the answer is:
sprigs
'shoots' is the definition.
(I have seen 'Small shoots ' mean 'sprigs' so perhaps 'shoots' could also mean 'sprigs')
'a prude when there are saints around' is the wordplay.
I cannot really see how this works, but
'prude' could be 'prig' (I've seen this in another clue) and 'prig' is located in the answer.
'saints' could be 'ss' (an abbreviation for saint written twice) and 'ss' is found within the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sprigs that I've seen before include "Sprays of leaves or flowers" , "Spray of leaves or flowers" , "Small stems or shoots" , "Small stems bearing leaves or flowers" .)
