óheimilri
The Icelandic word "óheimilri" is the dative feminine singular form of the adjective "óheimil." This adjective translates to "unlawful," "illegal," "invalid," or "unauthorized" in English. When used in its dative feminine singular form, it modifies a feminine noun in the dative case. For example, in a sentence, it might describe a "heimild" (permission or authorization) as being "óheimilri" (unlawful). The root of the word is "heimill," meaning "lawful" or "allowed," with the prefix "ó-" negating its meaning. Therefore, "óheimilri" signifies a lack of legitimate or legal standing for something that is feminine and in the dative case. Understanding the grammatical context is crucial to correctly interpreting its meaning in a sentence.
