óeðlilegrar

óeðlilegrar is the feminine genitive singular form of the Icelandic adjective óeðlilegur, which means unnatural or abnormal. It appears when a feminine noun is in the genitive case and is described by the adjective. In other words, óeðlilegrar functions as a grammatical form rather than a stand‑alone lexeme; the base word remains óeðlilegur and changes form to match case, number, and gender.

In Icelandic grammar, adjectives agree with the nouns they modify in gender, number, and case. The form óeðlilegrar is one such agreement pattern, used exclusively in contexts where a feminine noun is possessed or otherwise involved in a genitive relationship. Because it is a inflected variant, its meaning corresponds to the general sense of óeðlilegur—“unnatural,” “abnormal”—but its use is determined by syntax rather than by distinct meaning.

Etymology for the base adjective points to the negating prefix ó- attached to eðlilegur, itself related to eðli, meaning nature or essence. The overall sense is to express that something does not conform to nature or expected natural order. Óeðlilegrar thus appears in formal, descriptive, or literary Icelandic when a feminine noun in genitive is described as unnatural or abnormal.
