Holy book for primary school charity (6)
I believe the answer is:
psalms
'holy book' is the definition.
'psalms' can be an answer for 'book' (I've seen this before). I'm not sure about the 'holy' bit.
'primary school charity' is the wordplay.
'primary school' becomes 'ps' (this could be a standard abbreviation I've not previously seen).
'charity' becomes 'alms' (alms is a kind of charity).
'ps'+'alms'='PSALMS'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for psalms that I've seen before include "Religious songs" , "David's hymns" , "Devotional songs" , "Sacred songs or poems" , "Religious books" .)
