Allow some, given a blessing (6)
I believe the answer is:
enable
'allow' is the definition.
(thesaurus)
'some given a blessing' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ENABLE' is hidden in the letters of 'given a blessing'.
(Other definitions for enable that I've seen before include "Make possible, give the means to do something" , "Provide with means or opportunity" , "Capacitate" , "Give power or capacity to" , "Facilitate or make possible" .)
