Raise meaning of belief oddly abandoned (7)
I believe the answer is:
ennoble
'raise' is the definition.
(I know that ennoble is a more specific form of the action raise)
'meaning of belief oddly abandoned' is the wordplay.
'oddly abandoned' indicates alternate letters (letters in odd-numbered positions are removed).
'meaning'+'of'+'belief'='meaningofbelief'
The alternate letters of 'meaningofbelief' are 'ENNOBLE'.
(Other definitions for ennoble that I've seen before include "Make a count, perhaps" , "Make a peer" , "Lend greater dignity to" , "Raise status" , "Turn to peer" .)
