XLI

XLI is the Roman numeral designation for the number 41. It is formed by combining XL (40) with I (1), representing forty-one in the common subtractive notation used by Roman numerals.

In historical contexts, XLI is used to denote the year 41, such as 41 CE, in Roman dating and Latin inscriptions. The form can also mark the 41st item in an ordered list or sequence when Roman numerals are employed for enumeration.

In modern usage, XLI may appear as part of product names, model numbers, edition identifiers, or other cataloging schemes where the number 41 is meaningful. However, these uses are not standardized, and the exact meaning depends on the issuing organization or context.

Because XLI does not carry a fixed meaning beyond representing the value 41, ambiguity can arise without additional information. When encountered, XLI is usually clarified by accompanying dates, categories, or other contextual details that indicate whether it refers to a year, a position in a sequence, a version number, or another designation.
