Katkestav

Katkestav is an Estonian attributive participle derived from the verb katkestama, meaning to interrupt or cut off. Used as an adjective, katkestav describes something that causes an interruption, disrupts a process, or terminates a connection. The form is common in both everyday language and technical terminology, where it can modify nouns to indicate an interrupting function or effect.

In vocabulary terms, katkestav belongs to the class of present participles formed with the suffix -av, which conveys ongoing or resulting action related to the root verb. It is frequently found in compound nouns and noun phrases, especially in engineering, telecommunications, and electronics, where a device or signal may be described as katkestav if it interrupts a circuit or signal flow. Examples of such compounds include katkestav lüliti (an interrupting switch) and katkestav seade (an interrupting device). The word can also appear in broader contexts to speak about interruptions in processes, dialogues, or broadcasts, though in everyday language some speakers may prefer more common terms like katkestus for the noun form.

Related terms include katkestus (interruption) and katkestama (to interrupt). The adjective katkestav is typically inflected to agree with the noun it modifies in number and case, as is standard in Estonian grammar. Overall, katkestav provides a precise way to describe something that causes or performs an interruption within a system or sequence of events.
