Part in saga inane for second time (5)
I believe the answer is:
again
'second time' is the definition.
(I've seen this before)
'part in saga inane for' is the wordplay.
'part in' says the answer is hidden in the clue.
'AGAIN' can be found hidden inside 'saga inane for'.
(Other definitions for again that I've seen before include "second term" , "return" , "'Another time, once more (5)'" , "One more time, encore" , "Furthermore" .)
