Term:

SUPRA CITATUM

Definition:

Supra citatum (pronounced s[y]oo-pruh sih-tay-tuhm) is a Latin term used in legal writing to refer to a source that has already been cited earlier in the text. It means "above cited" and is often abbreviated as "sup. cit."

Examples:

According to Smith (sup. cit.), the new law will have a significant impact on small businesses.

As discussed supra citatum, the defendant had a prior criminal record.

The examples illustrate how "supra citatum" is used to refer to a source that has already been cited earlier in the text. In the first example, the author is referencing a previous citation to Smith's work. In the second example, the author is referring to a previous discussion of the defendant's criminal record. By using "supra citatum," the author can avoid repeating the same citation or information multiple times in the text.
