Prayer that gave the desperate four new heart (3,6)
I believe the answer is:
our father
'prayer that' is the definition.
'our father' can be an answer for 'prayer' (I've seen this before). I'm unsure of the remainder of the definition.
'the desperate four new heart' is the wordplay.
'the desperate' indicates an anagram (a desperate or pathetic spelling).
'new' indicates an anagram.
'four' is an anagram of 'ourf'.
'heart' with letters rearranged gives 'ather'.
'ourf'+'ather'='OUR FATHER'
'gave' acts as a link.
Can you help me to learn more?
(Other definitions for our father that I've seen before include "head of family" , "Pater noster" , "God" , "Early bit of devotion" , "Lord's Prayer" .)
