And so forth, for short (3)
I believe the answer is:
etc
'and so forth for short' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for etc that I've seen before include "And so on, in brief" , "'And the rest, in short (3)'" , "And so on, briefly" , "Etcetera (abbrev.)" , "And so forth (abbr)" .)
