Yläreunainen

Yläreunainen is a Finnish adjective meaning having an upper edge or upper border. The word is formed from the prefix ylä- meaning upper, and reunainen, derived from reuna meaning edge, with the -inen suffix to create a descriptive adjective. Together they describe objects, surfaces, or shapes that feature a distinct upper boundary or rim. The term is primarily descriptive and is used in everyday language as well as in design, architecture, and descriptive geometry contexts where the position of an edge matters. It is not a formal technical category in most disciplines, but serves as a clear modifier when the top edge is relevant.

In usage, yläreunainen typically modifies a noun to indicate the object that possesses the top edge. Common phrases include yläreunainen reuna to refer to the upper-edge border, and yläreunainen kehys to describe a frame located at the top of a structure or opening. The word is understood across Finnish speakers, though it remains relatively specialized and may be replaced with more precise technical terms in professional writings.

Examples:

- Laatikon yläreunainen reuna on vahvistettu. (The top-edge border of the box is reinforced.)

- Ikkunan yläreunainen kehys korostaa yläosaa. (The upper-edge frame of the window emphasizes the upper part.)
