Mánaðarins

Mánaðarins is a grammatical form in Icelandic that functions as the genitive singular definite form of the noun for month. It literally conveys “the month’s” and is used when indicating possession or attribution to a particular calendar month. The form is part of Icelandic noun inflection, where the base word mánuður (month) combines with the definite genitive ending to produce mánaðarins or a closely related variant in standard usage.

The primary role of mánaðarins is in written Icelandic, especially in contexts that require labeling or describing something associated with a specific month. It appears in calendars, yearbooks, almanacs, and monthly sections of newspapers or magazines, where headings or phrases refer to statistics, events, or features tied to the month in question. In such uses, mánaðarins helps to compactly express “the month’s …” without repeating a longer noun phrase.

In everyday speech, speakers often prefer more explicit constructions rather than relying on this grammatical form, especially outside fixed phrases or formal writing. Nevertheless, mánaðarins remains a recognized and standard part of Icelandic grammar for expressing month-related possessives in a concise, written style.
