Definition
"Et alii" is a Latin phrase meaning "and other men" or "and other people." It's the masculine plural form of "et al.", and it is used when referring to a group of male authors or a mixed-gender group where gender isn't specified. It is less common now because "et al." is typically used as a gender-neutral term. If you know that all members of the group are female, you use "et aliae." It suggests that the named individual is part of a group of people who worked on a shared project or writing.
