And others (2,2)
'and others' is the definition.
(short for 'et alia', 'and others' in Latin)
This is all the clue.
(Other definitions for et al that I've seen before include "'And others, to the old Romans (2,2)'" , "Latin notation meaning and others" , "... and other people (or things) (abbr)" , "Latin abbreviation meaning 'and others'" , "and everyone else)" .)
(Other definitions for oaths that I've seen before include "Swearwords" , "Expletives" , "Solemn vows" , "professions of loyalty" , "Imprecations" .)
