uregulär
Uregulär is a term used in linguistics to describe words or grammatical structures that deviate from the standard or expected patterns of a language. These deviations are often exceptions to general rules and are typically learned through memorization rather than by applying a predictable rule. For example, in English, the past tense of "go" is "went," which is an irregular verb. The regular pattern would be to add "-ed," as in "walked" or "played." Similarly, irregular plurals exist, such as "child" becoming "children" instead of "childs."
The presence of uregulär forms is common across many languages and is a natural part of language
