Promoted recent way of abbreviating a list (2,2)
I believe the answer is:
et al
'way of abbreviating a list' is the definition.
(way of abbreviating a list of people)
'promoted recent' is the wordplay.
'promoted' shows that the letters should be reversed in order (going up, in a down clue).
'recent' becomes 'late' (similar in meaning).
'late' back-to-front is 'ET AL'.
(Other definitions for et al that I've seen before include "Latin notation - late for others" , "along with others" , "'And others, to the old Romans (2,2)'" , "And the rest (Lat. abbr.)" , "Latin abbreviation meaning 'and others'" .)
