reglulegrar

Reglulegrar is a grammatical form found in Icelandic, used as the feminine singular genitive (and in some contexts other cases) of the adjective reglulegur, which means “regular” or “routine.” In Icelandic, adjectives agree with the nouns they modify across gender, number, and case, and reglulegrar represents one inflected ending within the feminine paradigm.

As a result, reglulegrar signals that the noun it describes is feminine and in a position governed by the genitive (or other compatible cases) within the sentence grammar. The form is part of the language’s standard adjective declension system, reflecting Icelandic’s broader pattern of inflection for adjectives in relation to the noun’s grammatical role.

Usage and occurrence vary by context. Reglulegrar can appear in formal writing, linguistic analysis, or historical texts where full grammatical agreement is discussed or demonstrated. In contemporary prose, its appearance is more limited to precise descriptive or academic contexts, rather than everyday speech, which tends to favor simpler or more common inflected forms.

Etymology and relation to other forms: reglulegrar derives from the adjective reglulegur, with the familiar Icelandic suffixing patterns that produce feminine, genitive, or other case forms. The underlying root links to the sense of rule, regularity, or regulation, aligning with related terms in Icelandic such as reglur (rules).
