Afterthought on charity recorded in hymns (6)
I believe the answer is:
psalms
'recorded in hymns' is the definition.
'psalms' can be an answer for 'hymns' (psalm is a type of hymn). I am not certain of the 'recorded in' bit.
'afterthought on charity' is the wordplay.
'afterthought' becomes 'ps' (as in a PS in a letter).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'charity' becomes 'alms' (alms is a kind of charity).
'ps'+'alms'='PSALMS'
Can you help me to learn more?
(Other definitions for psalms that I've seen before include "Sacred songs or hymns" , "Holy songs" , "Religious songs" , "Songs of David" , "Sacred songs or poems" .)
