engwinkelige

Engwinkelige is a Dutch adjective meaning “narrow-angled” or “sharp-angled.” It is used to describe shapes, margins, or other features that exhibit notably acute or tightly formed angles. The term appears in technical writing across disciplines such as geometry, botany, zoology, and architecture, where precise morphological description is important.

Etymology: The word is formed from eng (narrow, tight) and winkel (angle, corner), with the -ige suffix turning the root into an adjective. The construction is typical of Dutch compound adjectives used to characterize physical forms.

Usage: In geometry, engwinkelige is used to describe shapes with sharp corners or acute angles. In botany or zoology, it can refer to parts that end in a pointed tip or have converging margins, such as leaves or other appendages described as engwinkelige. The term is descriptive rather than classificatory, and care should be taken not to imply a strict taxonomic category unless the context specifies it.

Examples: An engwinkelige triangle is informally used to refer to a triangle with prominent acute angles. An engwinkelige leaf would have a distinctly pointed apex. In architectural descriptions, engwinkelige corners may be referenced to indicate tight, acute-angled edges in ornamentation or mouldings.
