Call to mind even parts of Greek prayer (9)
I believe the answer is:
recollect
'call to mind' is the definition.
(I've seen this before)
'even parts of greek prayer' is the wordplay.
'even parts of' means one should take alternating letters.
'prayer' becomes 'collect' (collect is a type of prayer).
The alternate letters of 'greek' are 're'.
're'+'collect'='RECOLLECT'
(Other definitions for recollect that I've seen before include "Look back on" , "in Scotland, mind" , "Recall to mind" , "Call to mind" , "Reminisce" .)
