otworem

Otworem is the instrumental singular form of the Polish noun otwór, meaning a hole, opening, or aperture. In Polish, otwór can refer to natural or manufactured openings, such as a bore hole, a doorway opening, or a surgical or anatomical passage. The instrumental form otworem is used in phrases that denote the opening as a feature of an object or in constructions with prepositions that require the instrumental case, for example z otworem centralnym, meaning with a central opening.

Etymology: The noun otwór is derived from the verb otworzyć (to open) and is related to the broader concept of opening. The exact historic development is discussed in Polish etymological dictionaries, but the association with opening and access is clear in modern usage.

Usage: Otworem appears primarily in technical and formal writing. It is common in engineering, architecture, geology, and anatomy to describe an opening as part of a component or structure. For example, część z otworem centralnym o średnicy 5 mm describes a part with a central opening of 5 millimeters in diameter. In everyday language, the noun otwór is more common than its instrumental form when used in isolation.
