Coming back often about present (9)
I believe the answer is:
recurrent
'coming back' is the definition.
(I've seen this before)
'often about present' is the wordplay.
'often about' becomes 're' ('re' means regarding or about. I am not sure about the 'often' bit.).
'present' becomes 'current' (similar in meaning).
're'+'current'='RECURRENT'
Can you help me to learn more?
(Other definitions for recurrent that I've seen before include "always coming back" , "Periodic" , "Happening often" , "Repeated again and again" , "seen frequently" .)
