Chevron |ˈ sh evrən| noun
a line or stripe in the shape of a V or an inverted V,
especially one on the sleeve of a uniform indicating rank or length of service.
• Heraldry: an ordinary in the form of a broad inverted V-shape.
• Architecture: a molding of continuous V-shaped patterns, common in Norman architecture.
ORIGIN: late Middle English (in heraldic use): from Old French, based on Latin caper ‘goat’ ; compare with Latin capreoli (diminutive of caper) used to mean ‘pair of rafters.’
A chevron (also spelled cheveron, especially in older documents) is an inverted V-shaped pattern. The word "chevron" is usually used in reference to a kind of fret in architecture, or to a badge or insignia used in military or police uniforms to indicate rank or length of service, or in heraldry and the designs of flags. The chevron symbol is also used on highway signs to guide drivers around curves.
The chevron occurs in early art including designs on pottery and rock carvings. Examples can be found approximately 1800 BC in archaeological recovery of pottery designs from the palace of Knossos on Crete in the modern day country of Greece. Sparta (Lacedaemonia (Λακεδαιμονία)) used a capital lambda (Λ) on their shields.
