The adjective nelikulmainen can be applied to various objects and concepts that exhibit a four-sided form. For example, a room might be described as nelikulmainen if its floor plan is rectangular. Similarly, a piece of land or a piece of furniture could be described using this term if its outline is a quadrilateral.

The usage of nelikulmainen is straightforward in Finnish grammar, inflecting according to the case and number of the noun it modifies. It serves as a useful descriptive term in everyday language and in more technical contexts related to geometry and design.
