Second last place (4)
I believe the answer is:
back
I believe this clue is a double definition.
'second' is the first definition.
(to second a motion is to back it)
'last place' is the second definition.
(as in the back of a queue)
(Other definitions for back that I've seen before include "Series of popular time-travel movies" , "Support a play - player" , "ago" , "Rear -- endorse" , "Help!" .)
