unregelmäßigem

Unregeläumtigem is the dative singular form of the German adjective unregelmäßig, which means not regular or irregular. As an adjective, unregelmäßig describes patterns, behaviors, or phenomena that do not follow a uniform rule or expectation. It is widely used across everyday language, as well as in technical and academic contexts such as linguistics, meteorology, and data analysis.

Declension and usage notes: German adjectives change form to reflect case, gender, and number. Unregelmäßigem appears in the dative singular when the adjective is declined with a strong (no article) or mixed pattern. For example, in unregelmäßigem Verhalten (dative neuter, strong declension) or in unregelmäßigem Muster (dative neuter, strong declension). After a definite article, the form becomes dem unregelmäßigen Verhalten or dem unregelmäßigen Muster, with the ending -en. With an indefinite article, one would typically encounter einem unregelmäßigen Muster, where the ending is again -en. These variations reflect standard German adjective declension rules.

Etymology and related forms: The word unregelmäßig is formed from un- (a prefix meaning 'not') and regelmäßig (regular). The form unregelmäßigem is simply the inflected dative singular of that adjective. Related terms include unregelmäßigkeit (irregularity) and unregelmäßige Verben (irregular verbs), which use the base adjective in different declension patterns.
