készüléken

készüléken is the locative singular form of the Hungarian noun készülék, meaning device or apparatus. It is a grammatical form rather than an independent word with a separate semantic field. The form is used to indicate location, roughly translating to “on the device” in English, and appears in phrases where the device itself is the reference point.

In use, készüléken marks the location of something relative to a device. For example: A hiba a készüléken van (The fault is on the device). A készüléken lévő jelző lámpa világít (The indicator lamp on the device is lit). It is common in technical writing, manuals, and equipment descriptions, where components, statuses, or faults must be described as located on or within a specific device.

Morphology and agreement: The base noun is készülék. By adding the locative suffix -en, the form készüléken is created, following Hungarian vowel harmony rules. Other nouns use the -on or -ön suffix in similar locative constructions, depending on stem shape and harmony.

Etymology: The form derives from the noun készülék, with the standard locative suffix -en applied to the stem. It reflects ordinary Hungarian grammar rather than a separate lexical item.
