Again, names one remembers (7)
I believe the answer is:
recalls
'one remembers' is the definition.
(I've seen this in another clue)
'again names' is the wordplay.
'again' becomes 're' (prefix meaning 'again').
'names' becomes 'calls' ('call' can be a synonym of 'name').
're'+'calls'='RECALLS'
(Other definitions for recalls that I've seen before include "Remembers" , "orders to withdraw" , "Brings to mind" .)
