zgasi

Zgasi is a form derived from the Polish verb zgasić, which means to extinguish or to switch off. It is used to describe the act of putting out a light, dousing a fire, or stopping a device from emitting light or heat. In standard Polish, zgasi appears as a third-person singular form used with an appropriate subject, as in On zgasi światło (He turns off the light). The corresponding past tense forms are zgasił (masculine) or zgasiła (feminine). The infinitive is zgasić, and the imperative form for a single command is zgaś.

Linguistic properties: zgasić is a perfective verb, and forms from it convey completed actions. This differentiates it from the imperfective gasić, which describes ongoing or repeated action. The prefix z- in zgasić signals termination or completion relative to the stem gas-/gas- in the sense of putting something out rather than sustaining it.

Usage and context: zgasi is common in everyday speech and in written instructions that request or report turning off a light or extinguishing a source of illumination. More general or softer alternatives for turning off electrical devices include wyłączyć (to switch off) or wyłączyć lampę. For candles or small fires, zdmuchnąć (to blow out) might be used, depending on the context.

Notes: zgasi does not refer to a widely recognized place, organization, or proper noun in standard usage. If encountered as a name in a fictional or local context, it would derive from such specific usage rather than from a general linguistic sense.
