et al definition
Full Definitions of et al. adv and others ('et al.' is used as an abbreviation of `et alii' (masculine plural) or `et aliae' (feminine plural) or `et alia' (neuter plural) when referring to a number of people) Synonyms: adv and elsewhere (used when referring to other occurrences in a text)
Used similarly to et cetera (and the rest), to stand for a list of names. Alii is masculine, so it can be used for men, or groups of men and women; the feminine, et aliae, is appropriate when the others are all female; but as with many loanwords, interlingual use (such as in reference lists) is often invariable.
