hälytyksin
Hälytyksin is a Finnish inflected form derived from the noun hälytys, which means alarm or alert signal. In standard usage, hälytys refers to a single alarm, while the plural hälytykset refers to multiple alarms. Hälytyksin, by contrast, is a less common form that is typically described as an older, dialectal, or formal variant used to convey the sense of “with alarms” or “by means of alarms.” Because of its rarity in everyday language, it is mainly encountered in historical texts, technical writing, or legal language rather than in contemporary speech.
Grammatical note and usage context: Finnish normally expresses the idea of “with alarms” with the adessive plural
Relation to related terms: The core concept remains the same as in hälytys and hälytysjärjestelmä (alarm system).
