Charlie soon with new side: made one of the Saints (9)
I believe the answer is:
canonised
'made one of the saints' is the definition.
'charlie soon with new side' is the wordplay.
'charlie' becomes 'c' (phonetic alphabet: alpha, bravo, charlie etc.).
'soon' becomes 'anon' (I've seen this before).
'with' means one lot of letters go next to another.
'new' indicates an anagram.
'side' with letters rearranged gives 'ised'.
'c'+'anon'+'ised'='CANONISED'
(Other definitions for canonised that I've seen before include "Anselm was" , "Held in great esteem by church" , "Sainted" , "Declared to be a saint" , "treated like a saint?" .)
