Beryl, possibly, a saintly individual? (5)
I believe the answer is:
stone
'beryl' is the definition.
(thesaurus)
'a saintly individual?' is the wordplay.
'a saintly' becomes 'st' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'individual?' becomes 'one'.
'st'+'one'='STONE'
'possibly' acts as a link.
Can you help me to learn more?
(Other definitions for stone that I've seen before include "Endocarp" , "Piece of rock - weight" , "Small rock" , "Rock; hard seed" , "Imperial unit of weight" .)
