óregluleg

Óregluleg is the feminine singular form of the Icelandic adjective óreglulegur, meaning irregular or not following established rules. The word is used to describe things that do not conform to normal patterns, such as certain grammatical forms, procedures, or events.

Etymology and form: The adjective is built from reglulegur, meaning regular, with the negating prefix ó-. In Icelandic, adjectives inflect for gender, number, and case to agree with the noun they describe, so óreglulegur has masculine forms, and óregluleg is used with feminine nouns, while óreglulegt appears with neuter nouns. Plural forms follow standard Icelandic adjective inflection.

Usage: Óregluleg is common in linguistics and language teaching to denote irregular inflection or conjugation. It can also describe irregular patterns in other domains, such as rules, processes, or events. In everyday language it is used to indicate that something does not fit the expected, rule-governed pattern.

Examples:

- Í íslensku eru margar óreglulegar beygingar sagnorða. (In Icelandic, there are many irregular verb conjugations.)

- Dæmi um óreglulega beygingu er notkun sagnorða sem breytist á ófyrirséðan hátt. (An example of irregular inflection is the use of verbs that change in unexpected ways.)

- Þessi atburður var óreglulegur fyrir várrar reglur. (This event was irregular relative to our rules.)

Etymology note: The prefix ó- signals negation, and reglulegur comes from a root meaning rule or regular pattern, rooted in historical forms of Old Norse. See also: reglulegur (regular), irregular (in linguistic terminology).
