Katkoina

Katkoina is a Finnish noun form derived from katko, meaning interruption, break, or outage. While the singular katko is common in everyday speech, katkoina appears primarily in formal, technical, or regulatory writing to refer collectively to multiple interruptions or outages. The form is used when enumerating incidents across systems or time periods, such as in reports on utilities, telecommunications, or public services.

Usage and nuance: Katkoina denotes multiple events and is typically plural in sense rather than a single occurrence. It is frequently found in sentences that discuss the combined impact of several disruptions, rather than describing a single outage. In contemporary Finnish journalism or official documents, katkoina can be used to express “several outages” or “a series of interruptions” in a compact form.

Examples: A report might state that multiple katkoina occurred within a given period, or that the network experienced several katkoina affecting service availability. In regulatory contexts, the term helps compress a list of disturbances into a single noun phrase.

Origin and related forms: Katko is the base noun for interruption or outage. Related terms include katkos (interruptions, often used in plural form), katkaisu (disconnection or cutoff), and other forms in the same word family. The suffix -ina is part of a productive pattern in Finnish that can form nouns indicating plurality, states, or roles in formal language.
