månens

Månens is the possessive form of the definite Swedish noun månen, meaning the Moon. It functions to indicate ownership or association with the Moon, and is used in phrases like the Moon’s surface or the Moon’s light. In Swedish, the possessive is formed by adding the suffix -s to the definite form of a noun. For månen, this yields månens.

The form månens appears in scientific writing, astronomy-related description, and literary or descriptive text when referring to something that belongs to or is characteristic of the Moon. Common examples include månens yta (the Moon’s surface), månens ljus (the Moon’s light), and månens kratrar (the Moon’s craters).

Usage notes: there is no apostrophe in this construction; the -s attaches directly to the definite noun. The base word månen remains the determiner, and månens completes the possessive meaning. While the indefinite form en måne can also express possession in other constructions (for example with en månens something in more elaborate phrasing), the standard direct possessive form for “the Moon” uses månens.

Etymology: the suffix -s is a common Swedish possessive marker that attaches to the definite form of nouns to indicate possession or association, a pattern found with many other nouns as well.

In sum, månens is the standard Swedish possessive form for the Moon when describing something that belongs to or relates to the Moon.
