Delayed returns with others (2,2)
I believe the answer is:
et al
'with others' is the definition.
(I've seen this before)
'delayed returns' is the wordplay.
'delayed' becomes 'late' (I've seen this before).
'returns' shows that the letters should be reversed in order.
'late' in reverse letter order is 'ET AL'.
(Other definitions for et al that I've seen before include "along with others" , "Latin abbreviation meaning 'and others'" , "And the rest (Lat. abbr.)" , "Latin notation - late for others" , "And the rest, to the old Romans" .)
