What is et all?

et al. is a Latin abbreviation meaning "and others." It is commonly used in academic writing and citations to shorten lists of authors when there are more than two or three authors.

Here's a breakdown:

• Meaning: "and others"
• Usage: Used after the first author's name in a citation to indicate that there are additional authors.
• Purpose: To save space and avoid listing every author's name, particularly when there are many authors.
• Format: Note the period after "al" as it's an abbreviation. The "et" is not an abbreviation, so it does not have a period.
• Example: Smith et al. (2023) indicates that Smith is the first author, and there are other authors who contributed to the work published in 2023.
